How to fix SVR records

Question

A newly installed Win2019 standard server and 5 win10 workstations was recently installed into an existing environment. As it turned out the old environment had an older VOIP phone system with every old computer using their phone to connect to the web and each other (peer network). In any event, adding the domain server, and not fully realizing the existing VOIP environment, the Windows 2019 server had DNS trouble. My solution was to separate the VOIP phones from the LAN. With new switches in place and new cables run everything settled in but was still losing connection from time to time and took longer to authenticate. I attempted to add one more system and the DC couldn't be found, though the new workstation received a proper address via the server DHCP and was able to ping the file server.

Checking the DNS everything looked correct, nothing out of place. When I ran DCDIAG I received one error

The DNS SRV records required to locate a AD DC for the domain are not registered in DNS.

• One of more of the following zones do not include delegatio0n to its child zone:

ENT.local

Local

. (the root zone)

Any assistance to correct this without rebuilding everything would be greatly appreciated.

Answer 1

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.
