We have about 25 branch location, which each location has a Windows DC configured as a Global Catalog server. At the OPS center we obviusly have the Exchange server and a DC/GC. Using TCPView, we have noticed that when we open Outlook it establishes a connection to one of our branch servers instead of our local server. I am assuming this is a connection to the remote Global Catalog service. Why would it be connecting to a remote server instead of the local, and how can we make sure all clients connect to their local GC server?
