We have a couple of people here who will occasionally lose access to a particular mapped directory.
We have VOl1, and we have SHARE, which is a subdirectory on VOL1. Both are mapped In windows 7, running Novell Client 2 SP1 for Windows 7, and occasionally they will lose access to the drive mapped to SHARE. If I go the the Map of VOL1, it works fine, I can look into all OTHER directories, UNTIL I try to open SHARE, at which point it all goes south.

When I try to disconnect and remap the drive, I get error c0000103.

A full reboot fixes this problem, which happens a couple times a week.

The drive is hosted on a server running Netware 6.5 sp8.
