Ok this is kind of hard to explain so I will try... I have two domains... lan.company.com and prod.company.com
lan.company.com -- LAN Servers and Workstations
prod.company.com -- Production servers
Both domains have 2 DC's running Windows 2003. The forest functional level for both is Windows 2003. I have established a two way transitive trust between the two domains. What I now need to happen is to have users be able to authenticate to resources on either domain (Namely the Domain Admins) so that file transfers can occur between the two. On all of my Windows 2003 servers I can add folder permissions for users from the other domain, however the problem I am encountering now is my Windows 2000 Advanced Servers cannot add folder permissions for users from the other domain. When logged into a Windows 2003 box, I can search from the other domain and pull up users, however from the Windows 2000 servers i cannot even see the other domain, hence i cannot search/add users.
I have spoken to MS briefly and they say that the Forest Functional level has nothing to do with this.
