How do you stop auto discovery in selected domains.
Posted on 2010-11-24
We have just upgraded our MS Exchange Server from 2003 to 2010 (running Hub Transport, CAS and Mailbox roles). Our AD forest has the root domain (we’ll call Domain A) plus three sub domains (let’s call them B,C,D). Our clients are running Windows XP and Office 2007. Only one domain (domain D) currently has exchange server installed however at least domain C did have exchange 2003 at one point in time. Since the upgrade computers in domain B and C are now asking users for logon credentials to the Exchange server in domain D. My issue is that users in domain B and C are configured to use exchange servers located in completely separate forest that have one way trust between either domain B or C and the local customer they support. If the users hit cancel outlook works properly but they are prompted to log into domain D’s Exchange once an hour. I’m looking for the best way to stop this from occurring while not disrupting the auto discovery/configuration features domain D. I hope this make sense and I realize it’s confusing but that’s the way this project was setup for various reason.
