We have a problem were replication from the primary ACS to the secondary ACS is failing. Yesterday morning, a scheduled replication worked just fine, but last night I attempted a manual "replicate now" and recieved the following error "Error (-16) trying to contact ACS 'ACS2'" and it has been failing ever since with the following error "Cannot replicate to 'ACS2' - server not responding". We even put a sniffer outside of the primary and are not seeing the replication traffic even attempt to go out of the primary. All settings have been verified over and over. What does the first error code that I mentioned mean?
I have this problem too.
