I see this issue every once in a while and thought it might make for a good tip. If you're running into errors trying to integrate MDT and ConfigMgr 2007 then this one's for you.
Issue
When trying to integrate MDT with a System Center Configuration Manager 2007 console via the option "Configure ConfigMgr Integration" on a Windows Vista or newer OS (Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2), the following error may occur:
Copied binaries to <ConfigMgr_Install_Path>\AdminUI\Bin
Copied extention files to <ConfigMgr_Install_Path>\AdminUI\XmlStorage\Extensions
Successfully connected to WMI namespace \\MASTER\root\sms
Located the provider for site <Site_Code> on server MASTER
Validated site server and site code.
Unable to compile <ConfigMgr_Install_Path>\AdminUI\Bin\Microsoft.BDD.SCCMActions.mof, rc = 3
Operation completed with warnings or errors. Please review the output above.
Cause
This issue is caused because ConfigMgr Integration needs to be run as an administrator.
Resolution
Right click on "Configure ConfigMgr Integration" and choose "Run as administrator".
