1. "There is a replication connection for your DC to itself. This is not valid, and the KCC and replication are ignoring it. You can delete it."

2. "open AD Sites and services. browse to the server listed in it. in the NTDS settings you will have a connection either named "automaticconnection....." or some wierd charachters. delete this connection. this is a scenario in which you have only 1 DC.
Note:Do not proceed with this process if you have more then 1 DC."
