stopped-extension-dll-exception

Exchange 2010 contacts in the are either no longer updated or created in the source domain. 

You proceed into the connector’s properties under Management Agents:

Review and confirm that the service account is correct:

Reviewing the event logs show the following errors displayed in the Application logs:

Log Name: Application

The description for Event ID 0 from source FIMSynchronizationService cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:
