This error just showed up in /var/log/messages

Jul  1 11:31:51 lp-pdc1 smbd[2305]: [2008/07/01 11:31:51, 0] 
Jul  1 11:31:51 lp-pdc1 smbd[2305]:   get_alias_user_groups: gid of user 
nobody doesn't exist. Check your /etc/passwd and /etc/group files

The user does exist

# grep nobody /etc/passwd

# grep nobody /etc/group

The GID of the domain account is  2004.   Should the local GID match the 
domain account?  I don't think that it has ever matched before and it 
was working fine
