Dcom errors from old exchange server
I am trying to rid my event log, on my domain controllers, of a DCOM connection failure. The DCOM reference is to a retired Exchange 2003 server which has been retired
DCOM was unable to communicate with the computer <Exchange 2003> using any of the configured protocols. Event ID 10009.
I need to know what I need to do to resolve these errors. It seems as if we only started seeing these errors after pointing exchange 2007 to a server 2008 dc from a 2003 dc.
I checked all dns records and also everywhere in ad and can't find any remnants of the old server. I am planning to upgrade to exchange 2010 soon and need to get these errors fixed ASAP.
Anyone have any ideas?
