PDC not syncing with Windows Time Source

Question

The Primary Domain Controller is not syncing with an external Windows Time Source, the local system clock is being used instead.

The following errors are appearing in the System event log on the PDC:

Below are the W32Time parameters from the Registry:

The error "The computer did not resync because no time data was available" is displayed when the w32tm /resync command is entered. I've checked GPOs and local security policy for settings described in the following link, none are configured:
error-message-run-w32tm-resync-no-time-data-available

UDP port 123 is allowed in the firewall.

I would be grateful for any assistance with this issue.

Answer 1

Might try a different source.

w32tm /unregister
net stop w32time
w32tm /register
net start w32time
w32tm /config /manualpeerlist:<ntp ip address> /syncfromflags:manual /reliable:yes /update
net stop w32time
net start w32time
then check
w32tm /query /source
w32tm /query /configuration
