SCCM client install fix

I recently had to add the SCCM client to a bunch of machines from a non-trusted domain to manage them because the group previously tasked with those machines could no longer handle it.  The majority of the machines installed correctly but some did not.  This fix takes a couple minutes but has fixed all of my client issues so far.

1. Check the CCMInstall\Logs\ folder.  Look at the logs, in particular look at ccmexec, clientIDmanagerstartup, and locationservices logs.  Also look at the ccmsetup folder for the ccmsetup.log and client.msi.log.  These logs can help you pinpoint the reasons for the installation problems.

2. If you see errors like "Unable to retrieve AMP for site code" in the CCMInstall\logs\LocationServices.log, the install may see more than 1 client certificate and not be able to pick one.  If you AD automatically enrolls the machines and issues a new cert, you can run mmc, add the certificates snap-in for the computer account, and remove the client certificates under personal.  If you can't delete those add CCMFIRSTCERT=1 to the client install options.  There are some other things you can do also to make sure the correct certificates are available on the untrusted client.

3. Uninstall the SCCM client if it already exists but isn't working correctly.  Go to a cmd window and change to the ccmsetup folder.  run ccmsetup.exe /uninstall.

4. (optional and I haven't seen any effects from not using it)  CCMClean does still work in SCCM 2007.  You can download the SMS2003ToolKit and copy just that one tool.  It helps remove registry links and orphaned files if any.

5. Cmd window and run "net stop winmgmt".  You may have to run this twice to get it to stop because sometimes the service will start again immediately.  As soon as it stops rename the c:\windows\system32\wbem\repository folder to oldrepository.  This will reset WMI when the service restarts which we will do with a reboot in a minute.

6. Delete the c:\windows\system32\ccm and ccmsetup folders on 32bit machines or the c:\windows\syswow64\ccm folder on 64bit machines.

7. Restart the machine and you will have a repaired WMI and ready for a clean install of the SCCM client.
