Hi,
We have a 2 node DAG stretched across 2 Sites with the Witness Server (non-Exchange Server) in the primary site and the Alternate Witness Server (non-Exchange Server) in the secondary site. A firewall exists between the 2 sites so we have put ANY / ANY rules in place between the Exchange Servers and between the Exchange Servers and Domain Controllers. My question is what network ports will the Exchange Server in the secondary site use to communicate with the Witness Server in the primary site? Remember the Witness Server is not an Exchange Server.
Regards,
Andrew
