Win 2K Server in NT4 Domain 1000 pts!!

I just installed a Win 2K server in my windows domain. I want to use it as my proxy server running Proxy 2.0 (no money in budget for ISA). My problem is that I cannot get my NT4 DNS to synchronize with my Win 2K server. I can log into the network from the 2K server, but none of the other machines can access the shared drives on the new server, nor can they get to the internet. How do I get this machine to allow the Primary controller to sync with it so that the other computers have internet access. I need my Exchange server to get to the internet.

Please help…..Thanks, Pat
