I'm confused, I thought I read in another message in this thread that it worked if the user is logged in? BTW, I'm wondering if any group policies are in effect that may be an issue? Another option is to try applying the GPO setting via Computer configuration, Windows settings, Security settings, Local policies, User right assignment "logon as a batch job" for the user account on the OU where the machine is? Another thing is the problem with using Word via COM - it requires c:\windows\syswow64\config\systemprofile\desktop to exist doesn't it? If you create it, does it make any difference? Does anything show up in process explorer? If you have an IIS 7 box involved is it running its application pool in 32-bit mode? (If you are using the VFP OLE DB Provider at all). So far Windows 2008 R2 has become a major PITA in some ways...

Good luck with this one and please post your findings when you resolve it!
