I have a domain trust in my environment and I want to add a user from domain-B to a shared folder on a server in domain-A. As a test, I added domain-b\user to the shared folder of dc2.domain-A.local which is a DC server. No problems there. Active Directory appears to be working.
However, if I go to a non-DC server than I cannot add the Trusted domain-B user to my domain-A server folders. Users from domain-B won't even populate the add user window when I try find users.
What am I missing?
