We are getting the following error every 5 minutes on our DC. Anyone have any ideas? We have read the TechNet article Q317210 and it didn't pertain at all to our situation. We have no child domains, we're running in AD mixed mode, and all of our Exchange servers are enterprise edition. The error started occuring after our ADC server was powered down then brought back up. Event ID: 8108 Source: MSADC Category: Service Controller The initialization process failed.
