I was looking into that command, but the problem is the domain I'm attempting to join is the same one that I'm unjoining.
Here is the project:

I am re-installing my Windows SBS2003 server, before I start the uninstall, I am going to run the script you guys helped me with, to unjoin the domain on about 20 pcs. After the server is installed, i am going to run the script with the netdom join command to joint he pcs to the domain. This is why I can't use the move command.

Basically, with the netdom Join command, upon boot up of the machine I would like to create an autologin and change that registry key. The acct that will be autologging would be the admin acct.
