I am having problems getting the MachineObjectOU="" setting working in the [identification] section of the unattend.txt. This works, and the domain is joined [identification] JoinDomain=drdl However, when I add... [identification] JoinDomain=drdl MachineObjectOU="OU = DRDL Laptops,OU = DRDL Standard Computers,OU = DRDL Client Computers,DC = drdl,DC=newgrp,DC = co,DC = uk" It not only fails to join the OU, but the domain as well! It is a windows 2003 domain, and the account being used to join the domain has the add workstation to domains priv. Not really sure what to try now, whether I need the JoinDomain entry as well? Any suggestions? Mat.
