Exchange 2003 and domain controllers

I have a Windwos 2003 domain (two domain controllers-both GCs) and a single
Exchange 2003 SP2 server. When I shutdown one of my DCs, users lose
connectivity with the mail server, despite the fact that there is another
DC/GC still running. Any ideas?

- Check the DSAccess tab of the server's properties in ESM - have you
manually selected a GC/DC, bypassing the process used by DSAccess to
discover and use these?
- Also run ExBPA and see if it flags anything.

Both domain controllers are listed as GCs--they were added automatically, not
manually.

What is ExBPA?

Look for it on the web or on microsoft.com.

Hello,

I have exactly the same issue here. Both DCs are listed in ESM, both DCs
are GCs.

It seems the first DC (DC1), holds something extra, as when DC2 is down,
Exchange still functions. However when DC1 goes down, no connectivity is
possible.

I have run the ExPBA tool, and can't find much.

Any more input on this would be appreciated? Thanks
