If this is recorded after an Exchange upgrade, EV100290 (Your Solutions - Fix Exchange 2007 SMTP Connectors with ADSIEDIT) describers how to use ADSIEDIT, and delete the "Main SMTP" connector manually.
A restart temporarely fixes the problem in my case. Still looking for a solution.
See the link to "TechNet Blog" for information on how to fix Exchange 2007 SMTP connectors with ADSIEDIT.
