We have a mixed workstation environment. NT4, 2000, XP. We have two domains, both with NT4 PDC's and BDC's. We do not use wins, since our network is all one logical segment. We set the workstation to use NetBIOS over TCP/IP. We have no problems with the 2000, and XP clients. However on any NT4 client, we are seeing that they cannot net view or connect to network resources. When we do a net view to a hostname, we get a system error 53. If we use the ip address or the fully qualified name, (\\hostname.xxx.com), it works. But if we ping the hostname, it is resolved by DNS just fine. We have tried forcing the node type to H, and tried it with node type B, with no luck. The problem is also strange in that it is not happening on all servers we try to connect to, even though some that work are identically configured to some that don't. We have also seen some just start working for no reason at all. This problem is also causing the NT4 clients to have to logon with cached account information, because the pdc is one of the machines having the problem. Our current workaround is to install NetBEUI on the workstations, but we would eventually like it to work with only IP.
