Rowland,

     I had a typo in my hosts file which is the reason my initial DNS
update failed. Corrected and joined again. Successfully joined and
updated DNS A record. I then made sure to give 'Domain users' a id of
10000. I am now able to run' getent passwd' and see all my domain users!
YES! However I still see something that confuses me. When I run 'id
tuser' I get the following.

uid=2155(tuser) gid=2002(domain_users)
groups=2002(domain_users),2004(remote_desktop_users_group),2001(BUILTIN\users)

Why is the uid 2155 and not 10001?
