My understanding of Ron's problem is that when he attempts to perform
a drive mapping either from afscreds.exe, afs_config.exe or via NET USE,
that the drive mapping apparently succeeds where succeeds is defined as
a drive letter is available for use.  However, any attempt to use that
drive letter to actually access AFS results in no information being 
returned by AFS to the Windows SMB/CIFS client.  This is true regardless
of whether the cell being accessed requires AFS authentication or not.

I have accessed Ron's cells from my system without experiencing the
problems he is describing.  If I remember correctly, Ron also has some
Novell client software installed on his machine.  I think there might
be some interaction between the Novell client software and AFS but I am
not sure.

Identifying the real cause of this problem is going to require someone
with knowledge of OpenAFS for Windows internals sitting down on a 
machine that suffers from the problem with a debugger to identify what
requests are being received from the Windows SMB/CIFS client and why
those requests are not being processed successfully.  At the moment I
don't have time to volunteer to do this.
