I have a Windows Server 2003 domain controller on which I also store user profiles. My user environment consists of Windows 2000 Pro and XP Pro clients (about 35). When a user tries to log on to the network, it takes upwards of 3-4 minutes for the logon to complete. It appears that the time is consumed in loading profiles and use settings. I've checked permissions and bandwidth and they seem ok. Any thoughts on where to look next?
