Windows 2000 Unattended – JoinDomain fai

When specifying JoinDomain in the unattended.txt file without specifying a user/password the system is installed correctly, but the JoinDomain command is not carried out. The computer account has already been created and the network connections are up and running correctly.

Does anyone out there have any ideas what the problem may be here? Or does on HAVE to specify a user/password??

Thanks
