NT to 2000 Migration problem

[Diblik]

Setup: NT and 2000 server environment and 98 and XP clients. Some XP clients have network connection problems at different times. Reboot the client and problem is gone for a while. Only thinh we've noticed is that the user name displayed in the Start menu window changes when the connectivity problem apprears. i.e Everthing working, the user name is displayed as Fred Smith (XP userID?), when problems arise it changes to fsmith(old NT userID?) and at that time has problems reaching network resources.
Any ideas what is causing this and how to resolve this?
TIA.

Upon further testing, the above statement is not always true. But we do see this error message in the event log when a user loses connectivity to network resources.
"No suitable Domain Controller is available for domain xyz. An NT4 or older domain controller is available but it can not be used for authentication purposes in the Windows 2000 or newer domain that this computer is a member of. The following error occured: There are currently no logon servers available to service the logon request" These happen a random times no pattern has been estaablished. - Any suggestion what to look for?

There appears to be connectivity problems between these clients and the Win2K server. They are able to see the NT4.0 servers, so I'd not think the network is congested, but look for traffic bottlenecks (do you have all these workstations and one NT4.0 server two or three hops from the Win2K server?) Or perhaps the Win2k server is becoming loaded and lets this connection request time out. How many simutaneous connections do you have to the Win2K AD server?

Problem solved - we added lmhost files to the clients that had the connection problems.
