Name resolution no longer works for a trusted domain

Hello. We have 2 domains with two way trust. Up until now I could just add users from the trusted domain to groups, etc. however, this stopped working. When we check the other domain, there are no problems there. they can find users from our domain.
Any thoughts?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
