I've set up an XP Pro Ed. computer on my companies domain, but when I try to log-in, I get an error that the domain could not be reached. If I log-in as administrator on the computer's "domain" I can browse the domain I'm trying to log-in. Another thing... when I'm browsing the network response is very, very slow... when it works. Most of the time Windows Explorer stops responding and I have to go to task manager to shut the thing off. I have tcp/ip, client for Microsoft Networks, File and Print Sharing, QoS Packet Scheduler, and NWlink ipx/spx/NetBIOS Compatible Transport Protocol. The domain controller for the domain in a Windows 2000 server.
