RPC server is unavailable

Hello,

 

I have this weird issue where I can't change domain controllers from ADUC or any active directory services. I'm not sure where to start troubleshooting this kind of issue. I can reach all other domain controller from the problematic DC but I can't do it from other DC's to the problematic DC. 

 

Any help would be appreciated.

    Please run;

    Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log
    repadmin /showrepl >C:\repl.txt
    ipconfig /all > C:\dc1.txt
    ipconfig /all > C:\dc2.txt
    ipconfig /all > C:\dc3.txt

    ipconfig /all > C:\dc4.txt

    ipconfig /all > C:\dc5.txt

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

        - BAMAZAD01 is DHCP assigned which should never happen for a domain controller, should always be static!

         

        - On BAMAZAD01 I'd add the server's own static ip address (10.100.5.4) listed for DNS, then do ***ipconfig /flushdns, ipconfig /registerdns***, restart the ***netlogon*** service

        - On BAMTORDC02 I'd add the server's own static ip address (10.10.10.182) listed for DNS, then do ***ipconfig /flushdns, ipconfig /registerdns***, restart the ***netlogon*** service

        - bardrdc02.txt file is for BAMDRDC02

        - dcdiag was run from BAMTORDC02 which seems to have a lot of problems. I'd check the event logs for related errors. Better run from BAMTORDC01
