There are no more endpoints available from the endpoint mapper - Run As Admin

Several servers in our environment are not able to "run as administrator" without receiving the message "There are no more endpoints available from the endpoint mapper." This is mostly happening with Server 2012. On Some of our Server 2016 machines, if you "run as admin" the program just doesn't start, so I'm assuming the same issue just without the pop up message.

I don't know what information is important. We have 3 DCs, AD DS is running. I've run a dcdiag and got some passes and some failures and warnings. I don't know which are important or even if that's relevant. I can past the report here if needed.

On the machines with the failure, Windows Firewall is on. They do have AV but we've tested with it off and it doesn't change it. We've restarted servers as well and they are all patched and updated.

I know they're old, and we're moving to change that before EOL on 2012, but we're stuck on a version of software and db that we're working to update but the vendor has given us problems, so "move to 2022 isn't in the cards...yet.

    Hello

    Thank you for your question and reaching out.

    This looks to be some replication issue with your AD DCs.

    1. Disable any Antivirus program or Windows firewall you may have for temporary purpose.
    2. Please verify that preferred DNS ip should be of DC.
    3. Please verify that the server application (Active Directory et al) has registered with the endpoint mapper on the RPC server (source DC).

    Please run;

    Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log (run on PDC emulator)
    repadmin /showrepl >C:\repl.txt (run on any domain controller)
    ipconfig /all > C:\%computername%.txt (run on EVERY domain controller)
    ipconfig /all > C:\problemworkstation.txt (run on problem pc)

    Also check the domain controller System and Replication (DFS or FRS) event logs for errors since last boot. Post the Event Source and Event IDs of any found. (no evtx files)

    then put unzipped text files up on OneDrive and share a link.
