User profile lost due to large amount of data requested from WIN NT server.
Cause:
Profiles stored on a Windows NT server must be synchronized between the server and client. Network calls made to the server result in a list of shared data being returned to the client. If too many network calls are made, the data buffer may not be large enough to contain a full list of the data requested. If a user profile is left off the partial list, the default user profile is used instead.
Solution:
There is no solution at this time. Microsoft is working on this problem.
