Could not look up dc's for domain Realm error in log.winbindd
 

I am having trouble getting my Linux server to join a Windows NT 4.0 domain properly. When using smbpasswd, I get a joined domain REALM successfully messages, but when a then set up a smb share and try accessing the share from a Windows client, I get prompted for a username and password. No username/password combination works.

I noticed in the log.winbindd file the following messages repeating every ten seconds:

[2003/12/03 08:00:36, 3] nsswitch/winbindd_cm.c:get_connection_from_cache(436)
Could not open a connection to REALM for \PIPE\lsarpc (NT_STATUS_DOMAIN_CONTRO)

[2003/12/03 08:00:46, 3] nsswitch/winbindd_cm.c:cm_get_dc_name(147)
Could not look up dc's for domain REALM

I also noticed that on the DC, REALM, my linux server gets registered so I'm fairly confident the server truely joined the domain.

My questions are:

1) Has anyone seen this before?
2) Is this a problem with my linux server configuration or is this something caused by a problem on my DC? I believe the \PIPE\lsarpc is a Windows pipe.
3) If it is something on the DC, would it have to be related to RPC only?

Thanks,
