I have recently restored 2 working Windows 2008R2 domain controllers (NPD-DC01 & NPD-DC02) into a test lab environment. I am getting the error "8457 The destination server is currently rejecting replication requests." in the Directory Service event log.
I have tried some suggestions already:
repadmin /options NPD-DC01 +DISABLE_OUTBOUND_REPL
repadmin /options NPD-DC01 -DISABLE_OUTBOUND_REPL
repadmin /options NPD-DC01 +DISABLE_INBOUND_REPL
repadmin /options NPD-DC01 -DISABLE_INBOUND_REPL
repadmin /options NPD-DC02 +DISABLE_OUTBOUND_REPL
repadmin /options NPD-DC02 -DISABLE_OUTBOUND_REPL
repadmin /options NPD-DC02 +DISABLE_INBOUND_REPL
repadmin /options NPD-DC02 -DISABLE_INBOUND_REPL
however I still cannot get them replicating - all network comms between the 2 are fine.
