Thanks for the response, I think I have it working. I recreated my answer file and while doing that I found the debugjoin setting. I set that in my unattend.xml file in the image and tried imaging the PC again. When I looked in the setuperr.log file, found in c:\Windows\panther\unattendGC I found the following [DJOIN.EXE] Unattended Join: NetJoinDomain failed error code is [1355] [DJOIN.EXE] Unattended Join: DsGetDcName test failed: 0x54b, last error is 0x0, breaking if debugger attached... [DJOIN.EXE] Unattended Join: Unable to join; gdwError = 0x54b Did a search on DSGetDcName test failed and found mention of using the FQDN, reimaged my test machine, added the FQDN and the PC was added to the domain. Looks like that corrected my issue. Not sure why the 64bit image requires the FQDN for the unattended setup while the 32bit image doesn't.
