This is the "NT" user manager for domains command?  Are on you an 
Windows server or workstation?

I have seen that message when the account for the machine or user is not 
working correctly  (e.g. if I try to logon as user from a trusted domain 
and the domain trusts were  not working..)

My guess is you logged in as Domain Administrator, the PC can't really 
figure out who are,  then tries to treat you as the local 
Administrator.   (you therefore would not immediately realize that there 
is a problem.)

  I would check a few things-
- Does "net groupmap..." look OK?
-You also want to make sure that domain administrator is listed in the 
domain admins group.  The net ... group ... command (not sure exact 
syntax) your help verify.
- Also look on the  logs for that machine on the samba server.
