I have 2 domains in the same forest. domain1.com and domain2.com. domain1.com also hosts the DNS. domain1.com was the first domain in the forest. When I try and add a user from domain2.com to the enterprise admin group on domian1.com it is successfully added. However, when I check the same user object from domain2.com, I do not see the enterprise admin group listed in the member of tab of this object.
If I go to the emember of tab of the user object and try and add a group, I do not see the entire directory and all the other domains in location.
