[Samba] strange PDC login problems

[Marcus Sobchack]

Hi,

on some W2K and WinXP clients we suddenly have problems to log into our
Domain. Error message from logfile (loglevel 2):

[2006/07/12 15:17:31, 2] lib/access.c:check_access(321)

It's a samba 2.2.3a-15 on Debian woody. We didn't change anything in
smb.conf or somewhere else.

Smb.conf: http://129.70.34.180/~schoppa/smb.conf
Level 4 log: http://129.70.34.180/~schoppa/log.pc-607


Any help would be great.
