VBS script error 1332

Hello,
I have this vbs script that's suppose to join the windows 7 to domain image at first boot. It's able to rename but at join domain part it fails and comes back with Join domain Failed. Error = 1332 Exiting script. Prior to syspreping the image, this script words perfectly fine but after sysprep it runs at first logon under SetupComplete.CMD in C:\windows\setup\scripts\setupcomplete.cmd I tell this cmd to run start c:\windows\setup\scripts\joindomain.vbs
