Fix Exchange 2007 SMTP Connectors with ADSIEDIT
Daniel Sarfati sent me an IM with an issue he had after he upgraded his Exchange 2003 organization to Exchange 2007 and removed the old Exchange server. I asked him to write it up so that we can all be aware of this.
I just installed Exchange 2007 on my brand new 64-bit PC… I was doing a migration from Exchange 2003 to 2007. I thought I had everything up and running so I uninstalled the old Exchange 2003 on the old server but never deleted the routing groups! When I tried sending an e-mail it would just hang in my queue, and when I go into “Send Connectors” and double-click the existing connector I had in there (that was the name of my old connector in my exchange 2003 enviornment) I was unable to add any “Source Servers” because it said that my exchange 2007 server was in a different Administrative Group.
I was completely stumped, until I read this error message in the event log:
Event Type: Error
Event Source: MSExchangeTransport
Event Category: Routing
Event ID: 5016
Time: 7:44:55 PM
The Active Directory topology service could not discover any route to connector CN=Main SMTP,CN=Connections,CN=First Routing Group,CN=Routing Groups,CN=First Administrative Group,CN=Administrative Groups,CN=Exchange,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=home,DC=local in the routing tables with the timestamp 12/31/2006 1:44:55 AM. This connector will not be used.
Since there was no GUI that showed me this, I had to use ADSIEDIT, and deleted the “Main SMTP” connector manually. To do so I launched ADSIEDIT and drilled down to the following location.
Once I did that I was able to add a new “Send Connector” in Exchange 2007 and not have it give me any errors! (And my e-mail went through)
