cannot add users from a domain

[stevej]

Hi,
I have a Windows 2000 server with AD installed. When I joined (and I was
able to join) a Windows 2000 Pro workstation to the domain I needed to add
a domain user to the power users group.
I used the snap-in to open the power users group, click to add the
domain user , which it saw, and when I try to finalize it I got the
following error:

(Suppose the user is "WS1")

Processing of the object ws1 failed with the following error:
The specified domain either does not exist or could not be contacted

Remember, I logged onto the domain with this workstation and was initially
able to click on this domain user?

Anyone?

Steve
