    Hi Andrew,

     

    We had the same issue today.   Uninstalling KB016623 resolved it as well.  I've logged it with Microsoft.  Will report back when they respond.

    We have almost similar issue where AAD App Proxy Servers stops authenticating Apps, Local User Logon, RDP via Domain user.
    We opened a case with Microsoft and have been told that Its a known issue and would be fixed in November 2022 Security update.

      Have you or Microsoft come up with an approach to mitigate the issue when it happens?

        freddy104 MS has advised not to patch the server until fix is released. They proposed a registry change, however it did not work.
