Exchange 2003 not seeing Domain Controllers / Global Catalogues in Directory Access tab
Posted on 2009-04-29
We have recently experienced a problem with an MS Exchange 2003 server, all of a sudden, the Information Store just would not mount. We digged through just about everything and then got to the Global Catalogue steps.
(The Exchange server is a domain controller itself along with the File and ISA server)
After around 15 minutes after setting the Exchange server as a Global Catalogue, we was able to start the Information Store.
Now we are curious as to what GC's the Exchange server could actually see and it turns out it can only see itself. (By right clicking the mail server > properties > Directory Access).
The File server is also set the Global Catalogue server and this hasn't been changed before/after the problem.
I can see the option to add additional GC's manually but we are curious why it cannot see any GC servers or Domain Controllers?
Also if we add servers manually to the list, will this result in any downtime?
