We have 3 servers running Windows 2003 in a child domain. DC1 & DC2 are my domain controllers and both are currrently global catalogs as well. The third server is NOT a domain controller and is only running Exchange 2003. The problem we are experiencing is that users are having problems with Outlook 2003 timing out connections to other global catalog servers in our enterprise. We have a root domain and 4 child domains; The root and 2 of the child domains have Exchange 2003 servers that both connect to the root domain via the same T1 line.
DNS shows all 3 servers as global catalog servers. We recently added DC1 as a GC for testing purposes...
In the Directory Access tab in the Exchange System Manager:
In "Domain Controllers" it shows all my domain controllers EXCEPT the 2 in its domain.
In "Global Catalog Servers" it shows all our global catalogs except the local one(s).
On the Exchange server in question, I am receiving Event IDs
8213 (System Attendant Service failed to create session for virtual machine Name . The error number is 0xc007054b.)
9153 (Microsoft Exchange System Attendant reported an error '0xc007056b' when setting DS notification.)
We are not running in native mode because we have some users still using Exchange 5.5 (there is a plan to remove it but it is in the near future, then we will go native)
