Okay don't ask me why but this same thing happened to me this weekend. I found that by manually adding the DNS server, which for me was the Win2k Active directory server, to the client's IP settings it would allow me to add the machine to the domain. I don't know why this fixed the problem for me because there are no DNS problems in the network, and I can access the server by name and ip without doing that. But, in order to add a computer to the domain, I had to put the dns in manually...

First thing to remember when migrating to Win2K...always always migrate the PDC first. Doing otherwise will result in headaches and complications. Do the PDC first (Win2K "acts" as a PDC until migration is complete), and then you can migrate the BDC's.
