Netware 6 SP4

Windows SP2
Client 4.9x SP2

I have a few users that are having a strange problem. I have a DLU policy
that sets them as an administrator on the PC. This has been working fine
until recently. For some reason. When the users login in. The system
creates a new profile for the user and adds a numeric extension such as
..000, .001, etc. They must setup their MS Office and outlook settings
again. Furthermore, when they try to look at the other profile directories
on the machine to get their files back, the system says that they do not
have access to view the other profile directories.

What can I do to troubleshoot this?
