Does anyone knows which ports should be open and in which direction between Skype for Business 2019 (Front End/Directors servers) and Active Directory servers?
Thanks for the help!
Best Regards

    Hi,

    You can refer to the link to get the list of required network to be opened with domain controllers:

    config-firewall-for-ad-domains-and-trusts

    Regarding the network flows for FRS and DFS service are required only between domain controller to ensure the sysvol and Ad replication.
