First off, I feel really stupid right now. In order to remove access to the global address list, I denied the Authenticated users from access. Now I get a message that I can't add or delete address lists because I don't have permissions. Obviously, I need to be able to manage, create, and modify lists. If possible, how can I reset the permissions on my Exchange Global Address List. I am running Exchange 2000 sp3 on Server 2000 sp4. Any help would be greatly appreciated as I am currently screwed.
