We have three servers running windows 2003, two can replicate fine however one cannot.
was trying to run adprep and got the error The schema master did not complete a replication cycle after the last reboot. The schema master must complete at least one replication cycle before the schema can be extended.
further investigation shows that the server has been disconnected past the tombstone life.
dcpromo /force removal fails and trying to seize any roles (RID, schema master) also fails both with the same error - target principal name is incorrect (it is not)
