samba - Mar 2006 - Samba Winbind wbinfo -u fails with "Error looking up domain users"

Hi,

After functioning correctly for more than 6 months suddenly Samba died : the
users and usergroups are not recognized anymore. Restarting the Windows 2000 ADS
(mixed mode) server and/or the Debian Samba server does not help. I even
re-added the server to the domain:

net rpc join -U Administrator reports a sucessful join.
Active Directory shows the Debian server's computer account
wbinfo -t reports sucess
wbinfo -g reports BuiltIn groups only
wbinfo -u reports ""Error looking up domain users"

I have followed all the steps in "chapter 12. Troubleshooting" of
"Using Samba", but no solution.

Any one any idea where to look?

TIA
