Using Novell Client 2 SP1 for Windows 7 | Windows 7 AMD64.

These two machines are two of the first W7 machines I have rolled out.
Other machines used by this group are XP SP3 with the most recent client.

Logins from the XP machines have never given any mapping problems.

The W7 machines give a resource erro on ONE of their drive mappings -
their shared group drive. Their home directories and other "utility
mapping we employ seem to work fine.

Any ideas about where to start looking for a solution/work around?

Looking at other threads I have asked them to try login from the tray
icon to see if that might work any different.
