[Samba] winbind cannot get domain SID, no authentication

Hi, thanks for your hints! I think, the network is not a problem, 
because all user can authenticate at the NT domain during login an see 
the shares. Ping and nbtstat also succed. The LINUX box was installed 
from scratch wiht yast using standard options. No special iptable rules 
were applied.
The configuration was working succesfully for serveral weeks without any 
Problems, but stopped working last Monday. Nothing has changed in the 
config at this time.

Does anybody know, what the winbind message "Retrying startup domain sid 
fetch for ... " really means and what could be the reason for it?  This 
ist the only permanently repeated message in the winbindlog.

Thanks Thomas
