samba - Aug 2004 - XP Pro problem/change to root user uid=0 gid=0 ????

Hi All,

I'm running 3.0.5 on Redhat as member server using winbind connecting to a
mixed mode win2k domain. secret are good, getent & wbinfo -u work fine. but
a user running xp pro cannot access the share, but can access subdirectories
therein. the client log file (log level is at 10) is repetitive and is full of
the following "Primary group is 0 and contains 0 supplementary groups
[2004/08/31 13:17:29, 5] smbd/uid.c:change_to_root_user(281)
  change_to_root_user: now uid=(0,0) gid=(0,0)"

I'm a bit lost after seeing him connect to subdirectories but not the share.
Now we've removed and re-added his workstation to the domain and I'm out
of ideas. Below is my nsswitch.conf, pam.d/login and my smb.conf

I'm very grateful for any assistance.

Mike
