exchange 2010 server
Posted on 2016-09-27
Our exchange 2010 server can't get external email. Internal outcoming /incoming is working fine.
I did restart Transport Service in exchange server - not working.
I did run dcdiag.exe on our AD server 2012 - all passes except below:
Starting test: Replications
[Replications Check,ADS-01] A recent replication attempt failed:
From VMS-DC1 to ADS-01
Naming Context: DC=BFServer,DC=local
The replication generated an error (1256):
The remote system is not available. For information about network troubleshooting, see Windows Help.
The failure occurred at 2016-09-27 00:50:43.
The last success occurred at 2016-02-10 05:49:02.
5519 failures have occurred since the last success.
Overall, what else I can try? It does not look like Replication error is the cause of the email issue.
