RE: Mapped Drive Connection to Network Share is being disconnected

I am having a similar problem with any machine with XPpro SP2 on the network.
None of the Windows 2k or 98 machines drop the mapped drives.

Once they are dropped, the user has to log off and on again before the
mapped drive becomes available again.

Do you think this is the same problem you describe.
