domain issue and user accounts

[firehawk]

Hi, new here and hope someone can help

I have done this before dozons of times but for some reason its just not working on my test environment. :)

I want to add a domain user locally on a workstation which has been joined to the domain.

I have a DC set up in WS2003 EE SP1.
I have a workstation with WS2003 EE (then added SP1)

I then joined the workstation to the domain and it seems to join fine.
I can log on using a domain user account on the workstation fine.

but now I want to add the domain user "test" on to that workstation locally.

So, I log on as admin locally on the workstation, pull up computer management and in the local users and groups, in the administrator group I click add.

if I click on the locations button, I can ONLY see the local machine and not the domain. :(

I have no idea why this is happening. I have done this tons of times on other networks/computers and its always been fine. Unless I have missed a step somewhere?

Firewalls are off, connecting the computers via a router.

im stumped.

I did use the "net localgroup administrators "domainName\domain users" /add switch and that seems to add the domain to the "locations" list but still, this is kind of not really a proper solution to the problem.

anyone have any ideas? :)

Thanks in advance ;)
