This is a simple environment. Single DC (W2003) with a single MS Exchange 2007 (W2003) server.
On various occassions I notice in the app log and error that references event id 4011 (Source = MSExchange Availability). The supporting details of the event references a domain that is not part of our system and states....
Process 7436[w3wp.exe:/LM/W3SVC/1/ROOT/EWS-1-129129871989577068]: Configuration for forest NOTMYDOMAIN.COM was not found in Active Directory. Run the Add-AvailabilityAddressSpace command in the Exchange Management Shell for an Exchange Server 2003 Active Directory forest.
I don't understand why I would need to run something in my AD for a domain that is not part of our environment. On the other hand I am concerned if I do not do anything there is a bigger problem at hand.
Any suggestions as to what this is really about and what (if anything) I should do?
