I have a production ACS system that has multiple external NT domains for authenticating users.

We are bringing up a new ADS domain that I need to authenticate against. We have created the trust. The domain shows up in the domain list. When I go to map a NT group to a ACS group, the NT group list is empty.

The other domains show their NT groups.

What is also noteworthy is that when I log into the ACS server desktop and try to the see the foreign domain groups via user manager, I get a "domain cannot be found". When the server admin logs in (he administers both domains), he get a list of the foreign groups in the user manager.

What could be preventing ACS from see the groups in the external domain?

Thanks for any assistance.
