The first thing to check is if your trust relationship in unidirectional or bidirectional.

If it is unidirectional then that would explain the things. In this case, you will need to have a bidirectional trust relationship.

If you already have a bidirectional trust relationship then you might want to make sure that DCs and AD replication in both domains are in healthy state using dcdiag and repadmin commands. That would help: http://www.ahmedmalek.com/web/fr/articles.asp?artid=23

Also, use NSlookup to make sure that you can do properly the DNS resolution from both domains and that, from each domain, you can do a DNS resolution for resources in the other domain: http://social.technet.microsoft.com/wiki/contents/articles/29184.nslookup-for-beginners.aspx

You can also validate the trust relationship in both directions and see if any error is thrown.
