I have a very frustrating problem. I have a Windows XP
Professional Workstation on a Windows 2000 Server
enviroment that every night whether it is turned off or not
gives me an error message the next morning when I try to
access the mapped network share. I have to run the
following command and sometimes it will sucessfully connect:

net use f: /delete
Net use f: \\server\data

Sometimes I get asked for a username and password other
times I am not. Can anyone shed some light on this
frustratung problem?

Thanks,

Dustin
