We are running Exchange 2003 and 2007 and Windows 2003 Server. On one of our 2003 servers, messages are being caught up in the 'awaiting directory lookup' queue.
Does anyone know -
1. How can I tell which DC's Exchange is using for directory lookup?
2. I can ping all the DC's in our site, but is there any specific tool I can run to find out if it is servicing GC lookups for Exchange fine (I know thers is DCDiag etc)?
3. Is there any way to get Exchange to change the DC's it's using?
Questions apply to both Exchange 2003 and 2007 pls.
