Unable to sync server to new NTP server

Question

Hello, Recently added two Windows 2016 domain controllers and made one of the them the new PDC (the intention is to demote the old 2012 servers soon). After the change, when updating DNS settings in two file servers, they are unable to sync to the NTP and time keeps changing to CMOS, also state is pending (see screenshot) Registry was configured in the PDC with type NTP, the rest uses type NT5DS. If reverting at least one of the DNS server settings to the old server then the file server synchronizes properly. Other servers in the domain don't have this issue. ![81291-image.png][1] [1]: /api/attachments/81291-image.png?platform=QnA Thank you!

Answer 1

Yes, Windows Time service is running. See below the results for those commands:

C:\Windows\system32>w32tm /query /source
10.x.x.x
(10.x.x.x is the IP for the PDC)

C:\Windows\system32>w32tm /query /configuration

Answer 2

That doesn't appear to have been run on the PDCe

also 0x8007054b == ERROR_NO_SUCH_DOMAIN so the new PDCe may be broken for other reasons.

No, the commands were run on the offending server.
Running the same commands on the PDC shows the following:

C:\Windows\system32>w32tm /query /source
tick.usno.navy.mil,0x1

Answer 4

Please run;

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

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