exchange server ports RRS feed

  • Question

  • dears,

    I have an exchange DAG located on one AD site with a domain controller.

    I created antoher site on different subnets with a DC there and the witness server is located there too.

    Im facing a problem that my exchange server is going down when i created the second site, now that i removed it it is working again.

    can you advise on which ports should be opened between my exchange server and the domain controller located in the second site?

    best regards

    All of them. Its not supported to have any port blocking between Exchange Servers and Exchange and Domain Controllers

  • Hi eg1559,

    Because other Windows services may use different ports, and you can create a custom connector to use other ports, so, we don't suggest you block any ports on your server.
