I am trying to add a Macintosh to a W2k server mixed node environment. We are running TCP/Ip and so is the Mac. Added the computer account and the user account to the network. Mac client is running DAVE. We have a Linux box as the gateway/firewall and the Mac can get on the internet just fine. What step am I missing? The Mac connected just fine when NT 4.0 was the domain controller, but haven't been able to connect since upgrading to W2K server. Any ideas?
