reset domain administrator password on a win2k8r2 DC

Forgot your domain admin password? Whoops.

On a Win2k8r2 domain controller:

  • Boot with the installation media (or any other WinPE kind of media)
  • Go to the System32 directory
  • ren utilman.exe utilman.exe.bak
  • copy cmd.exe utilman.exe
  • Reboot the system
  • At the logon screen, press Windows Key + U. A command prompt will start.
  • net user Administrator "!mynewpass123"
  • Log in, start a command prompt.
  • del utilman.exe
  • copy utilman.exe.bak utilman.exe

done :-)

dns config on a domain controller (best practice)

Sometimes i tend to forget…

As a best practice on a domain controller, always add 127.0.0.1 (locahost) as a DNS server, just not as the first entry!

Windows 2008R2 and SCCM 2007 SP2 - Pt7 - Deploy operating systems (Windows 7 SP1)

Another great feature of SCCM is deploying operating systems.
Although you can deploy a whole range of Windows versions, i’m going to focus on deploying Windows 7 with SP1 included.

In order to support Windows 7 (with SP1), you’ll going to have to download and install an extra update from microsoft here kb2489044.

Also, there is an extra issue to deal with.
With the update above installed, it would be possible to support and deploy Windows 7 to known systems, meaning systems that are allready member of the domain and registered with sccm.
Since we’re talking about deploying Windows 7, it is very well possible that a brand new system has been unboxed and you want to deploy it right away. So we’re dealing with unkown systems here.
To support unkown systems, we need to have at least update R2 installed for SCCM 2007 SP2. But update R3 is out so we’re going to install R3.
Before installing R3, there’s a prerequisite here: kb977384.
Then download and install: Update R3 for SCCM 2007 SP2.

Build a reference system
The most easy way to deploy an image is to build a reference system first. This means a plain Windows 7 installation with only the essential software installed that you want to have on every pc. A virtual workstation, like one in VMWare, will do just fine.

  • Download the latest installation media from Microsoft. As of this point: Windows 7 with sp1 included.
  • Create a virtual machine with only the basic requirements (1cpu, 512MB ram, 24GB thin provisioned disk will do just fine). As of Windows 7 we don’t need to think about the fact that hardware we are going to deploy this image to is likely to be using a different HAL since Windows 7 will do a HAL autodetect on boot. If you don’t know what that means, don’t bother :)
  • Boot the virtual machine and boot from the installation medium
  • Keep all the settings default. At the point where Windows setup asks for a username and computername press Control+Shift+F3
  • Windows now boots into audit mode. More on that on my website: Windows 7 Audit Mode
  • Do not close the small sysprep (”Hulpprogramma voor systeemvoorbereiding”) window!!!
  • Now install all the software you want. You can reboot as many times as you like, just don’t close the sysprep window. In my case i’m only installing:
    • vmware client installation
    • from a dosprompt: “powercfg -setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c” to set the power profile to high performance. This prevents the client from going into standby every time (very annoying!)

    As you’ll see, after every reboot, Windows will automatically reboot into Audit Mode again.

  • Copy the content of “C:\Program Files\VMware\VMware Tools\Drivers” to a shared folder on your SCCM server, e.g. “\\sccm01\clientdrivers\x86\vmware client\”. This is to ensure we have the appropriate drivers for this system. We’re going to need this to create bootable media for capturing this system.
  • Leave the computer as it is for now

Create capture media
Capturing the installation of the reference system is done through capture media.
This is basically a Windows PE cd/dvd or usb stick that copies the content of the harddisk to a .wim file on an external disk or network share.
When you think about that, it’s easy to understand that the PE environment needs to have access to the local harddisk and network interface.
And that’s why you have to make sure these drivers are available and that’s why we have copied al the drivers to “\\sccm01\clientdrivers\x86\vmware client\” in the last step above.
Now we have to update the capture media with those drivers.

  • From the SCCM Console, expand site database, computer management, operating system deployment, drivers and rightclick drivers and click Import
  • Choose “import all drivers in the following network path” and browse to “\\sccm01\clientdrivers\x86\vmware client\” and click Next
  • In the overview you’ll see that all drivers for the audio, mouse, scsi controller and network controllers are found. Click Next
  • Click “New Package”, Name = “VMWare Client” and Drive Package Source = “\\sccm01\clientdrivers\x86\vmware client\”, select “Update distribution points when ready” and click Next
  • Do not update any boot images at this point and click Next, Next, Close
  • From the SCCM Console, expand site database, computer management, operating system deployment, Boot Images and rightclick “Boot Image (x86)” and click Properties
  • On the tab “Windows PE” select “enable command support (testing only)” and then click the yellow icon to import drivers
  • Add all drivers, one by one (although only the scsi and network drivers are really relevant) . Eventually click OK and click YES to update the distribution point, Next, Next, Close.
  • Repeat the steps for the x64 boot image
  • From the SCCM Console, expand site database, computer management, operating system deployment, Task sequences, rightclick Task sequences and click Create Task Sequence Media
  • Select “Capture media” and click Next, select “CD/DVD set” and click browse to select an output .iso file (e.g. sccm2007capture.iso) and click Save and click Next
  • Click on Browse and select the boot image that matches your installation (x86 or x64) and click OK and Next, Next, Close

Capture the image

  • Make sure you have a shared folder on your sccm server e.g. “\\sscm01\images” to store the image on.
  • If you are working with a physical system, make sure you have burned the iso that has been created above. If you are working with vmware, put the iso on the datastore.
  • Put the capture media in the dvd player. Autorun will start.
  • “Welcome to the Image Capture Wizard” click Next
  • Destination = “\\sccm01\images\win7sp1referencesystem.wim” and specify the correct network credentials so that after rebooting into PE mode, the capture media knows how to store the image on the SCCM server! Click Next
  • Specify the information asked, click Next and Finish
  • You may see some screens popping up, just wait and the client will reboot automatically and you´ll see the System Center background and the capture in action
  • If all goes well, you’ll eventually get a message “Image successfully captured …”. press OK and the client will reboot. You can then power it off.
    If you let it run, it’ll do some sort of “unattended” installation, but it’s pretty useless since the machine isn’t instructed properly what to do (e.g. like joining the domain, install extra components etc).

Import the image in SCCM

  • Now that the image has been captured, we have to import it to SCCM
  • From the SCCM Console, expand site database, computer management, operating system deployment, Operating System Images and rightclick “Operating System Images” and click “Add Operating System Image”.
  • Point to the share where the images is located, e.g. “\\sccm01\images\win7sp1referencesystem.wim” and click Next, Next, Next, Close
  • Rightclick the just created Operating System Image and click “Manage Distribution Points” and click Next, select “Copy the package to …” and click Next, select your SCCM server and click Next, Next, Close.

Prepare the PXE server

  • Expand (in order) site database, site management, <your site>, site settings, site systems, <your server> and rightclick your server, select New Roles, Next, select “PXE service point” + Next
  • Click yes at the warning.
  • Select “Enable unkown computer support” and click OK at the warning dialog
  • Deselect “require a password …” and click Next, Next, Next, Close

Create the Configmgr package

  • Expand site database, computer management, software distribution and packages
  • Rightclick Packages, select New, Package from Definition and click Next
  • Select the “Configuration Manager Client Upgrade” and click Next
  • Select “Always obtain files from a source directory” and click Next
  • Select UNC path and your SCCM server should have a default share called \\<SERVERNAME>\sms_<SITECODE>\ with a client folder in it, so in my case “\\Sccm01\sms_vl3\Client”. Point to that directory and click Next and Finish
  • Rightclick the just created “Microsoft Configuration Manager Client Upgrade 4.0 ALL” package and select “manage distribution points” and click Next
  • Select “Copy the package …” and click Next
  • Select only the primary distribution point and click Next, Next, Close
  • Rightclick the just created “Microsoft Configuration Manager Client Upgrade 4.0 ALL” package and this time select “Update distribution points” and click Yes

Specify network access
If we’re going to boot from the network later on, and we need to access the distribution points, we need to authenticate.

  • On the SCCM console expand site database, site management, <your site>, site settings, client agents and rightclick “Computer Client Agent” and select properties.
  • Click on the “Set” button at Network Access Account.
  • Specify the Administrator account for now and click OK and OK
  • As of a security perspective this might not be best practice but for now it’s OK

Pretty much everything is covered now.
So if we would unbox a new computer, connect all the wires and execute a network boot, this is what we would see:
sccm_pxeboot.jpg
In red: The WDS (or SCCM) server is not responding.
In green: the mac address of this client.

What we need to do next is create a task somehow to deploy Windows 7 to this computer.

Create a collection

  • On the SCCM console expand site database, computer management, collections, and richtclick collections en click on “New Collection”.
  • Name = “Deploy Win7 with SP1” and click Next
  • No membership rules are needed so just click Next and click OK on the warning.
  • Click Next Next Close.

Add the computer (mac address) to the collection

  • On the SCCM console expand site database, computer management, operating system deployment, computer association, and richtclick computer association and click on “Import Computer Information”.
  • Select “Import Single Computer” and click Next.
  • Provide the desired computername, e.g.”win7-001”, and provide the mac address of the client. Click Next, Next
  • At “Choose Target Collection” select the collection that we’ve created above “Deploy Win7 with SP1”, Next, Next, Close

Create a Task Sequence

  • On the SCCM console expand site database, computer management, operating system deployment, Task Sequences, and rightclick Task Sequences and click on “New, Task Sequence”.
  • Select “Install an existing image package” and click Next.
  • Give the sequence a name like “Install Windows 7 with SP1 on new systems” and select the boot image that corresponds with the architecture, e.g. x86, and click Next
  • Select the Image Package (which is your previously captured image) and at Image select “All Images” (this is because a normal Windows 7 installation also contains a 100MB boot partition). Fill in the rest of the information, like the license code and type, and click Next.
  • Specify the domain to join with the right credentials and the OU you want to place the computeraccount in and click Next
  • Click Browse to select the Configuration Manager package. Click Next.
  • Deselect all Stage Migration settings, we’re not going to do that on new systems. Click Next
  • “Don’t install any software updates” and click Next, Next, Next, Close.

Modify the task sequence
There is a small “bug” in the default task sequence if you ask me.
If you edit the task sequence, you’ll see that the network configuration is taking place before the device drivers are installed. This should be in reversed order.

  • On the SCCM console expand site database, computer management, operating system deployment, Task Sequences, and rightclick the sequence created above and click on Edit.
  • Select the green item called “Apply network settings” and drag it just below “Setup Operating System”

With that out of the way there is something with the partitioning to worry about:

  • Select the green item called “Partition Disk” and in the “Volume” overview, you’ll see two volumes. One Primary volume with a fixed size of 100MB and one Priamary volume with a fixed size of the original disk of the reference system. Select that volume and click edit. Select “Use a percentage…” and set it to 100%. Click OK and OK.
  • Select “Apply Operating System” and make sure that at “Apply operating system from a captured image” image 2-2 is selected
  • Select “Apply data image 1” and make sure that at “image” image 1-1 is selected
  • Drag task “Apply data image 1” above “Apply Operating System” and beyond “Partition disk”

If you want you can add custom taks or edit. Just look around, very cool! :-)
Hint: look at the partitioning settings and when formatting the disks, make sure you select quick format. Saves a lot of time!

Assign (advertise) the task sequence to new computers

  • On the SCCM console expand site database, computer management, operating system deployment, Task Sequences, and rightclick the sequence created above and click on Advertise.
  • Click on the browse button to select a collection and select the “Deploy Win7 with SP1” collection that we have created before. Also select “Make this task sequence available to boot media and PXE”. Click Next, Next.
  • At the Distribution Point screen, make sure you also select “When no local distribution point is available, use remote distribution point” and click Next, Next, Next, Next, Close.

If you go to the “Deploy Win7 with SP1” collection, doubleclick on the “Win7-001” and go to the advertisements tab, you’ll see that the “Install Windows 7 with SP1 on new systems” is assigned to this computer.

That’s it. Perform a network boot and sit back!

Windows 2008R2 and SCCM 2007 SP2 - Pt6 - SCCM and Software Updates (WSUS)

SCCM is capable of managing Software Updates, but it relies on WSUS for that. So you need to have that installed. If you’ve followed this guide, you have.
Whereas for WSUS you need to configure group policies, for SCCM everything runs through the SCCM client so you don’t need to worry about that.

Enable the Software Updates part in SCCM

  • Expand (in order) site database, site management, <your site>, site settings, site systems, <your server> and rightclick your server, select New Roles, Next, select “software update point” + Next
  • At the Active Settings window, check the “Use this server as the active software update point” + click next
  • Enable a schedule (1 day for now) and click next
  • Select classifications and click next
  • Select the products and click next
  • Select and deselect the appropriate languages and click next
  • Next, Next, Close

If you want to change any settings later, expand site database, site management, <your site>, site settings, component configuration and rightclick “Software Update Point Component” and click properties.

Start initial synchronization

  • Expand site database, computer management, software updates, Update Repository
  • Rightclick Update Repository and click Run Synchronization

Download the System Center Configuration Manager 2007 Toolkit V2 and use Trace32 to tail the logfile “c:\program files (x86)\Microsoft Configuration Manager\Logs\wsyncmgr.log” to watch the progress of the synchronization.

Configure the Software Updates Client

  • Expand (in order) site database, site management, <your site>, site settings, client agents
  • Rightclick Software Updates Client Agent and click properties
  • Adjust the schedule to 1 day
  • On the tab Update Installation select “Enforce all mandatory deployments” and set it to 1 hour. Also enable the “Hide all deployments from end users”. Click on OK

Create templates

  • Expand site database, computer management, software updates, deployment templates
  • Rightclick deployment templates and select new deployment template.
  • Name it “Windows 7 updates”, since we’ve created a collection of Windows 7 stations previously, and click next
  • Browse for the “All Windows 7 Systems” that we’ve created in Part 4 of this SCCM series, click OK and next
  • Select Suppress notification, since the end user doesn’t have to be bothered with this, and set the Duration to 1 hours, which means that updates will be deployed fast. Click next
  • Select Workstations to suppress the reboot notifications for the end user and click next
  • Select the “Generate Operation Manager alert when a software update installation fails” and click next
  • Select “Download software updates from distribution point and install” on both scenarios and click next
  • Click next on the “SMS 2003” window
  • Next, Close

Now before you can continue, you have to make sure that the software updates are synchronized with Microsoft. Use the Trace32 mentioned above.

Create a search folder and an update list

  • Expand site database, computer management, software updates, update repository, search folders
  • Rightclick search folders and select “new search folder”.
  • Name it “All Windows 7 updates” and press OK
  • Step 1 = Product, Step 2 = Windows 7, Step 3 = enable all subfolders, step 4 = “All Windows 7 updates” and press OK
  • Rightclick the “All Windows 7 updates” search folder and click on refresh
  • In the right pane, select all updates and then rightclick and select Update List.
  • In the window that opens select “Create a new update list” and name it “Windows 7 update list” and press next, finish, next, close

    (with this method you can add extra updates to the list later too)

Deploy the Update list to the template

  • First, we need to create a share on the SCCM computer to where the updates can be temporary downloaded to.
  • Create something like “E:\tmp_downloads”
  • Share this folder and add “domain admins” and the sccm computeraccount to the sharing and ntfs permissions with full control
  • In the SCCM console, expand site database, computer management, software updates, update lists AND deployment templates so you see them both.
  • Drag the “Windows 7 update list” on to the “Windows 7 workstations” deployment template
  • If there are any license terms you need to accept, you’ll have an extra window in where you need to accept the license terms
  • Next, at “create a new deployment package”, specify a name like “Windows 7 update package” and point the package source to the share you’ve created (”\\SCCM01\tmp_downloads”). Enable “Enable binary differential replication” and click Next
  • Browse to select your distribution point, which is your sccm server, and click Next
  • “Download the updates from the internet” and click Next
  • Choose your languages but they should already match your template and click Next
  • Choose a schedule or leave it to the defaults and click Next
  • Next, Next (updates will be provisioned)
  • Close

Now from time to time keep updating your list and drag it to the deployment template. Since you’ve enabled binary differential replication, clients that already have received most of the list, will only transfer the differential.
Best practice is to create a couple of deployment templates, based on the priorities, so for example you can deploy critical updates faster than other updates.

Windows 2008R2 and SCCM 2007 SP2 - Pt5 - Distribute software

One of the main reasons (amongst others) that you are going to use SCCM is probably to distribute software to clients and servers on your network.

To enable this functionality

  • Expand (in order) site database, site management, <your site>, site settings, site systems, <your server> and on the right pane, rightclick “ConfigMgr distribution point” and properties.
  • Select “Allow clients to transfer content from this distribution point using bits, http, and https ….)” and click OK

Add a package to the inventory

  • First, let’s download a nice utility called DoPDF. On that url, you’ll find a setup file. I’m saving it in the Downloads folder but in a subfolder called “DoPDF 7”.
  • On the SCCM console, expand (in order) site database, computer management, software distribution, packages
  • Rightclick packages and click “new -> package” and fill in the details (DoPDF, 7.x, DoPDF, English) and click Next.
  • Select “This package contains source files” and click on Set, “Local Drive …” and point to the folder where you’ve downloaded the msi file to. Click OK, Next, next, next, next, finish, close.

Add a program to the package
After creating the package, you can add one or more programs to the package.

  • Expand “DoPDF DoPDF 7.x English” and beneath that rightclick Program. Select New Program.
  • Name will be (again??) “DoPDF 7”, for commandline, browse to the directory and select the “dopdf-7.exe” but append the commandline with “/VERYSILENT /NORESTART”. These are however specific commands for this utility, so you’ll have to adapt for other installations. Click Next
  • Enter an estimation of the disk usage (so that the sccm client can abort the installation if a computer runs out of space) and the time the installation will approximately take. Optionally select specific platforms. Click Next.
  • At the environment level, you can specify whether the setup will run as the user currently logged on or with administrative rights. I suggest you set it to administrative rights and do not select “Allow user to interact with this program”. Click Next, Next, Next, Finish, Next, Close.

Distribute the package to a distribution point
There can be more than one distribution point in a bigger organization but in this case we only have to distribute it to one point.

  • Rightclick Distribution point and click “manage distribution points”. Click next, “copy the package to the new distribution points” + Next, select your SCCM server + Next, Next, Next, Close.
  • Expand “package status” untill you see your SCCM site, refresh, and in the right pane you’ll see the status of your package being copyed to your distribution point. “Installed” means it is transfered to the distribution point.

Assign the package to clients

  • Expand (in order) site database, computer management, software distribution, advertisement
  • Rightclick advertisement, New, Advertisement. I’m naming this taks “DoPDF 7.x for Windows 7 Clients”. Click on browse to select the DoPDF 7.x package. And click on browse to select a collection, in my case “All Windows 7 Systems” and click Next.
  • On schedule you can schedule this deployment to a specific date or time, you can even enable Wake-on-LAN if you want (but you’ll have to enable wake on lan on the site properties first!), but for now click on the yellow icon that looks like a sun and select “as soon as possible” and press OK. Click next.
  • On Distribution Point select “download from distribution point and run locally” on both occasions and click next, next, next, Finish, next, close.

The default polling interval of your clients is 60 minutes, so with a maximum of 60 minutes the installation will start.
You can set the interval higher at site settings -> client agents -> computer client agent properties. For this test environment it’s safe to set it to a really low value like 1-5 minutes, but in a bigger environment you don’t want to stress the SCCM server and your network.

Windows 2008R2 and SCCM 2007 SP2 - Pt4 - Collections

If, after installing SCCM 2007 SP2, you take a look at the collections (under Computer Management), you’ll see that it’s not really up to date. Servers up to Windows 2003 and workstations up to Windows XP are available, but no Windows 2008 (r2?) or Windows 7 is present.
If you are going to delegate tasks to systems, you might want or need some more finegrained collections.

Collections are based on query’s, so in order to create a new collection for Windows 7, we’re going to do the following:

  • Rightclick Collections, New Collection
  • Name and Comment: “All Windows 7 Systems”, click next
  • Click on the yellow database icon, set name to “All Windows 7 Systems”, resource class is “System Resource” and click on Edit Query Statement.
  • Go to the tab Criteria
  • Click on the yellow icon, click on the Select button
  • Attribute Class = “System Resource”, Attribute is “Operating system name and version”, click OK
  • Operator = “is like”
  • Value = “%Workstation 6.1%” (which basically means, if you combine it with the operator “is like”, that it must contain “Workstation 6.1”)
  • Click OK, OK, Next, Finish
  • Rightclick the new “All Windows 7 Systems”, click “Update Collection Membership”, rightclick again and click refresh. The Windows 7 systems should appear.

Use your imagination to create all sort of collections you might need. Like systems with 512MB ram or less, systems with de specific type of cdromdrive, anything you can imagine.

By the way: Windows 2008 R2 would be “%Server 6.1%” as value

Windows 2008R2 and SCCM 2007 SP2 - Pt3 - Basic configuration

After the previous article, the installation of SCCM 2007 SP2, it’s time to do the basic configuration.

Basic configuration, find clients on the network
Log on to the Configuration Manager Console

  • Expand (in order) site database, site management, <your site>, site settings, site systems, <your server> and on the right pane, rightclick “ConfigMgr management point” and properties. Select “Allow devices to use this management point” and click OK
  • Rightclick Boundaries, select New Boundary, add a description (e,g, “VL3 boundary” to match it with the sitecode of your installation) and set type to “Active Directory Site”. Then select the sitename that has been configured in Part 1 of this Windows 2008R2 and SCCM 2007 SP2 series, OK, OK
  • Rightclick your site (the one under site management) and click properties. Go to tab Advanced and make sure “Publish this site in Active Directory Domain Services” and “Publish the default management point in DNS (Intranet Only)” are selected. Press OK.
  • You have to define some sort of discovery method so that SCCM can find clients and/or servers (you can also select other methods but i’m going for “Active Directory System Discovery”). Go to Discovery Methods and rightclick “Active Directory System Discovery”, properties, select “enable ..” and click on the yellow icon that looks like a sun. Select ‘Local Domain” and make sure “Recursive” is enabled and press OK. In the window that opens select the topmost item which should be the name of your active directory domain (in my case: “tailspintoys”) and press OK and OK again.
    Goto the tab polling schedule and select “custom schedule” and recur every 5 minutes + OK.
    Press OK to save these settings and quit the window.
    Give SCCM some time to actually discover the computers. Then expand site database, computer management, collections, all systems. Rightclick on “all systems” and select “update collection membership”. Wait a little. Then rightclick again and select “refresh”. You should see some computers now, or at least your domain controller.

    Remember that you always have to “update collection membership” and then “refresh” to see new computers.

Push the sccm client to clients and servers

  • Expand (in order) site database, site management, <your site>, site settings, client installation methods.
  • Rightclick “Client Push Installation”, properties.
  • Click “enable client push installation…” and click on OK at the popup window.
  • Select servers, workstations and domain controllers and also “Enable client push installation to site systems”
  • On the tab accounts, click on the button that looks like a sun and specify the administrator account (best practice is that you will not use that in a production environment!!), OK, Apply, OK

Go back to your collection of computers, “update collection membership” and then “refresh” and after a while the table “Client” will say YES to indicate the SCCM client has been installed.

Create some reports
After the client has been pushed to all desired systems, you want to do something with the collected information.

  • Expand (in order) site database, site management, <your site>, site settings, site systems, <your server> and rightclick your server, select New Roles, Next, select “reporting point” + Next, Finish, Next, Close.
  • Expand (in order) site database, computer management, reporting, Reports and rightclick a desired report, e.g. “Computers in a specific workgroup or domain” and select Run.
  • Or rightclick Reports and select Run. A browser will open and you can click through all the reports. Cool uh?

Windows 2008R2 and SCCM 2007 SP2 - Pt2 - Install SCCM 2007 SP2

Continuing the previous article, once you have all the prerequisites in place, you are ready for the installation of SCCM 2007 SP2.

Extend the active directory schema
First, you have to extend the Active Directory Schema. The best way to do this is to log on to on the domain controller that holds the schema master role and start an elevated dos prompt. Then run the following program from the SCCM 2007 SP2 cd (or files on a share):

"\smssetup\bin\i386\extadsch.exe"

If you encounter errors like these:

<09-11-2010 17:53:11> Modifying Active Directory Schema - with SMS extensions.
<09-11-2010 17:53:11> DS Root:CN=Schema,CN=Configuration,DC=stpauls,DC=qld,DC=edu,DC=au
<09-11-2010 17:53:11> Failed to create attribute cn=MS-SMS-Site-Code.  Error code = 8224.
<09-11-2010 17:53:11> Failed to create attribute cn=mS-SMS-Assignment-Site-Code.  Error code = 8224.
...
<09-11-2010 17:53:12> Failed to extend the Active Directory schema.

.. you probably have some replication issues to deal with first. Or, in my case, the domain had one or more child domains and those domain controllers were offline. Make sure they are online and reachable.

Add the computer account to the System container

  • On the domaincontroller, start Active Directory Users and Computers.
  • Make sure you have advanced features enabled (View, Advanced Features)
  • Rightclick the “System” container, properties
  • Security, Add, Object Types, enable Computers + OK, type in your SCCM computername and click OK
  • Make sure your SCCM computername is selected, then click full control, followed by advanced
  • Locate your SCCM computeraccount, select it and click on Edit, set Apply to to “This Object and all descendant objects”, OK, OK

Install SCCM

  • From te splash screen run the “Run the prerequisite check”
  • If you’ve followed my previous article and you’ve installed SQL, enter your servername (my case: SCCM01) in the first two fields and press OK
  • Checks will run and if all goes well you’ll see “All required prerequisite tests have completed successfully”

Windows 2008R2 and SCCM 2007 SP2 - Pt1 - Getting all the prerequisites right

I’ve been talking to some people about SCCM recently and it seems to be difficult to understand the whole process to set it up right. Therefore i’m going to share my experiences.
This first part covers all the prerequisites and setting them up.

1 - The (simple) setup

I’m going to presume an active directory is already present.
My (vmware) setup:

  • DC1
    • Windows 2008 R2 with SP1
    • 1vCPU, 512MB ram, 1×32GB harddisk (C:)
    • 10.10.10.100
    • role: the one and only domain controller responsible for the domain “tailspintoys.com”.
  • SCCM01
    • Clean installation with Windows 2008 R2 with SP1 added to the “tailspintoys.com” domain
    • 2vCPU, 2GB ram, 2×32GB harddisk (C: and E:, D: is the dvd player)
    • 10.10.10.125
    • role: going to be the SCCM 2007 SP2 server, also acting as SQL, WDS and IIS server. More on that later.

2 - Windows 2008R2 Roles, Features and configuration for SCCM

Features
On SCCM01, let’s add some features first. Start the server manager, go to features, add features:

  • select feature “background intellingend transfer service (BITS)”
    • yes, “Add Required Role Services”
  • select feature “remote differential compression”
  • next, next
  • since we’ve added the webserver role (that came with BITS) we now have the chance to add extra role services for this role. Add the following:
    • “Webdav Publishing”
    • “ASP .NET” (yes, add the dependencies)
    • ASP (you’ll need that for the reporting of SCCM, at first i forgot which led to “HTTP error 404.3 - Not Found” errors)
    • “Windows Authentication”
    • “IIS6 WMI Compatibility”
  • next, install, close

Configure webdav
Now we have to configure the webdav properties for the default website in IIS. You can do it later after SCCM is fully installed but you have to do it at some point so why not do it now.
Microsoft has a document on this but here it is in short:

  • Start the IIS manager
  • Expand till you see the default website. Click on it.
  • In the middle pane, doubleclick “Webdav Authoring Rules”
  • In the right pane, select “enable webdav”, followed by “Webdav Authoring Rules”, followed by “Add Authoring Rule”
  • “All Content”, “All Users”, “Read” + OK
  • In the right pane, select “Webdav Settings”
    • Allow anonymous property queries = True
    • Allow Custom Properties = False
    • Allow property queries with infinite depth = True
    • Allow hidden files to be listed = True
    • In the right pane, click Apply
  • Close the IIS manager

Roles
As SCCM needs WSUS and relies on the PXE server from WDS, we have to install some additional roles. Go to the server manager, roles and add the following role first. You have to install the WSUS role later, you can’t select it with other roles at the same time. So first:

  • Windows Deployment Services. Just next, next next, ….

Now add the following role:

  • Windows Server Update Services (yes, add the dependencies). Next, next, next, ….
  • If you are wondering why installation takes such a long time, notice the window on your taskbar. An additional screen with “Welcome to Windows Server Update Services 3.0 SP2 Setup Wizard” has opened.
    • I’ve placed the wsus data on E:\WSUS and i’m using the Windows internal database, but other circumstances may apply.
    • Click through the setup till the end and click Finish
  • When the roles are installed, click Close. A new window to configure WSUS will open.
  • Cancel these configuration steps.

Configure WDS

  • From the Administrative Tools, start Windows Deployment Services.
  • Expand servers, Rightclick SCCM01 and select Configure Server
  • I’m storing the data on E:\RemoteInstall but change to match your environment
  • I’m selecting “Respond to all client computers (Known and Unknown)” but that’s also a choice
  • Don’t select “Add images to the server now” and Finish

If you are not going to run DHCP on this server, skip this next 3 steps. But if you are going to install the DHCP role on this server then do the following prior to installing the DHCP role:

  • Rightclick the SCCM01 server and select Properties
  • Go to the tab DHCP
  • Select the first option “Do not listen on port 67”.

Optionally: Install and configure the DHCP role on this server
This is optional. You can run DHCP on any other server too.
But if you are installing DHCP on this server (i’m sure the basic configuration doesn’t need additional explaining here), all you have to do is go to the WDS settings (above) and on the DHCP tab select the “Configure DHCP option 60 …”. Then restart the DHCP service.

Configure DHCP that runs on a different server
If you are running DHCP on a different server in your network, configure options 66 with the ip-address of the WDS server and option 67 with “boot\x86\wdsnbp.com”. “wdsnbp.com” is a little utility that automatically determines the platform so it will automatically switch to x86 or x64 if neccessary.

At this point, all the Windows “internal” software related prerequisites on the SCCM01 server are in place.

3 - Other prerequisites

Associate a subnet with a site
To define a boundary for SCCM later, it is important to have a subnet defined and match it with a site in active directory.
So if you have not defined a subnet yet (if you have done a plain active directory installation, you won’t), then log on to the domain controller and do the following:

  • Open Active Directory Sites and Services
  • Expand till you see Subnets
  • On Subnets, rightclick and select “New Subnet”
  • Prefix: in my case: 10.10.10.0/24 and select a site object from the box below (on a plain installation it’s just Default-First-Site-Name)

Install SQL server for SCCM
To start with: i’m far from an expert on SQL. Beste practices may be different. But to get things up and running, the following will work.
SCCM won’t work on Express editions of SQL, so make sure you have a full version (get trial version here). I’ve read rumours that SCCM 2007 SP2 doesn’t work on SQL 2008 R2 but it does!

  • On the domain controller, start “Active Directory Users and Computers” and create a group called “SQL Admins” and make this group member of the group “Domain Admins”
  • Also create a new account called “sql2008r2”. Make this user member of the group “SQL Admins”
  • On the SCCM server, go to the server manager, add the feature “.NET Framework 3.5.1 Features” and add the required dependencies. Next, Install, Close
  • Reboot the server prior to installing SQL to be sure you don’t have pending installation tasks
  • Run setup.exe. On the first page, there’s a System Configuration Checker. Run it, all checks should be OK. If not, correct them
  • Click on Installation on the left side of the screen, then select “New installation …”
  • Keep everything default unless stated otherwise.
  • At “Setup Role”, choose “SQL Feature Installation”
  • Only the “Database Engine Service” is really required, but you also want to select “Reporting services” to create all kinds of cool reports from SCCM later. Also select “Management Tools - Complete”.
  • At “Server Configuration”, click on “use the same account for all services” and supply the “sql2008r2” account created in the second step.
  • At “Database Engine Configuration”, click “Add the current user” followed by “Add” and also add the “SQL Admins” group.
  • Complete the rest of the installation of SQL

Your system is now ready for the installation of SCCM 2007 SP2

Disable ipv6 and Teredo

To completely disable ipv6 and the Teredo interface:

reg add "HKLM\SYSTEM\CurrentControlSet\services\Tcpip6\Parameters" /v DisabledComponents /t REG_DWORD /d "255" /f

“255” decimal stands for 0×000000ff hexadecimal.
However, this isn’t listed here: http://support.microsoft.com/kb/929852/. Nonetheless this setting suits my needs best.
