Server 2016 Std DNS BPA Errors

I have three DNS errors and a large number of warnings which I cannot resolve.  There is also a problem with Windows Time which cannot resolve the time server and defaults to the CMOS clock. ...

Thanks very much Dave Patrick for your reply.  Unfortunately the time sync didn't work.  I think there is a slight sequence error in the commands. So I have changed the unregister command to be after the net stop command.  I have changed the time server IP to 3.uk.pool.ntp.org which pings successfully.

 

The serious issue as I see it are the DNS errors.  I suppose I can always set the CMOS clock accurately occasionally but any further assistance in resolving the NTP issue gratefully received..

 

Results below:

No, the sequence is correct. You can ignore errors depending on the state of service. From the results above the time configuration is being overridden by a policy. However if you're moving on to other issues then 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

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

      Looks Ok to me. I'd suggest removing the router address as forwarder. There are quite a number of DCOM errors in system event log that may need attention. As to anything DNS I'd check the system event log for related errors since last boot.

        Hi Dave
         
        Thanks for the response and apologies for the delay in replying. I don't come to site too often and don't like making some changes remotely.
         
        I've removed the router IP from the list of forwarders but still have the same BPA results.
         
        When I ran the DNS configuration wizard I selected 'small network' there being only nine users and 12 devices hence only creating forward lookup zones. Should I try rerunning the wizard selecting large users and hence creating forward and reverse lookup zones?  This is the only server on the network and as such has the FSMO roles.
         
        Thanks.
