We have a school environment currently one of our pc labs is unable to
always get their appropriate drive mappings. I have updated the lab this
summer (Win XP SP2 client 4.91 sp2) and they are not able to consistently
grab their drive mappings.

Out of 27 computers about 24 will work correctly and the others won't the
student will restart and has about a 50/50 chance of getting in correctly.

The servers are NW6.5 SP4 - which they have been for a while now. The
only change on the server side is a new server was added this summer - but
it is for backups/tech stuff only.

I have another pc lab (Win2000) that connects through the network in the
same spot that has now problems connecting.

What might be the cause of this??
