Level

Comments
 
To clean this error, you must delay the ADWS service:
1. CMD
2. sc config ADWS start= delayed-auto
From a support forum: Are both domain controllers also GC (Global Catalog)? Please verify that they are fully synchronized. Generally speaking, the 1202 event indicates the machine became a GC but ADWS couldn't establish a connection to it on the GC port. ADWS will keep retrying, so if there's a subsequent 1200 event ("is now servicing the specified directory instance") for the GC instance, it was a transient issue and solved itself.
I got this in Active Directory Web Services log on a W2k8 R2 DC in a domain with a W2k3 R2 server holding all FSMO roles. The event is followed by informational events 1006 "Active Directory Web Services is advertising." 1004 "Active Directory Web Services has successfully started and is now accepting requests" and 1200 "Active Directory Web Services is now servicing the specified directory instance.
See EV100100 (a Microsoft discussion thread called Edge Transport - RODC's - ADWS and ADAM Errors) - it has some comments about a particular instance of this error.
From a support forum: "I had the same issue here on a TMG server and I resolved it by disabling the Active Directory Web Services service.

If the configuration storage server is setup on a different computer, the ADAM instance on the TMG firewall server will be disabled. You can disable the ADWS service on the firewall to prevent that this service fills your event log. (This service can't reach ADAM on the local machine because it's disabled, and is complaining about it.)

If your ADAM instance is on the same box, it might be something else that is causing this issue."
