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.

If  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.You can safely ignore this message.

From the event log I can see event id 1200 also has occured.You can safely ignore the errors events as ADWS start before AD starts and hence the event is logged.

Regarding the KCC Event ID 1311 is logged in the Directory Service event log when the replication configuration information in Active Directory does not accurately reflect the physical topology of the network.
