An error occured while reconnecting g: to \server_name

Netware Services: Mulitple connections to the server or shared resource by
the same user, using more then one user name are not allowed.

I hope someone can help me with this. I just set up a 6.5 server with XP
Pro boxes. I log on and map the drives for user A. If I then switch to
user B and explore the drives I get this error. The only fix I find is to
disconnect the mappings for user A and remap for user B. The big problem
is I will have more then one user assigned to the pc and I can't map and
remap these drives all the time.
