I'm running into an issue where users log into their Win2k/NT4.0
workstations, download their profiles off of our Samba 2.2.5 server,
map home, miscellaneous shares, and printers on it, and then randomly
during their session they cannot open these remote devices.  They
receive an "Access Denied" message when trying to do anything with
the server.  The log then fills with tons of the following:

[2002/08/16 10:34:56, 2] smbd/uid.c:change_to_user(138)
  change_to_user: Invalid vuid used 101

It's fixed when they log out and back in.  Anyone have an idea of
what this is?  I tried to search Google and the Samba archives, but
didn't get very far.  We do not use winbind, and all of our users
have UNIX user accounts of the same name as their accounts in the NT
4.0 domain.  It's so sporadic that I haven't even had the time to
nail down a more detailed log (this was a lucky catch at a time when
debug was at level 2).

Any ideas?  Thanks!
