Is it possible to transfer the pdc role to the additional domain controller and check if its syncs with the ntp server and dc and clients are able to sync? If i remember well you need to reset values for the previous server holding the the pdc role to sync with hierarchy? Maybe this way you can verify if its a server issue or a network issue. Just saying my opinion i only tested that in a test lab.

It might help to know what these IP addresses refer to, but I noticed something else that you might want to look in: some of the startup parameters look totally weird. Do you have a time GPO applied? If so, unlink it. The default values are (unfortunately) wrong.

These are very non-default, and must have been set somehow. Default value here is 48h or 0x2A300 seconds.

Some of the other values seem off as well. Somebody did something [biggrin]

So after running that again, I see that the PDC has set itself back to NT5DS instead of NTP

my understanding is the PDC, as master of the heirarchy, should be set to NTP and pull from an external NTP server... and that everything else in the domain should be nt5ds and pull from the pdc?

What about the values in the Config (registry) section? Better now?

Does time sync work if you configure the external NTP?
