We are having some weird issue going on out AD server is gradually running ahead of time currently it's 2 mins ahead. It is gradually getting increased last time we did few things which i can't remember that bring back to sync but we forgot what we did. It seems to be like every 2 month AD starts to runs forward. So far we tried resync manually set ntp settings through w32 command on cmd but nothing worked. We also tried manually setting time by going under Data and time settings but magically after setting time if we hit ok it somehow automatically get back to previous result which is 2 min ahead.
P.S: Right now it's 2 min but we are guessing after 15 days it's gonna be 3 min ahead.
Any suggestion or resolutions ? We are using physical server not under VMs.

2021-12-02T15:37:35.65+00:00 Should it be checked or unchecked?

2021-12-02T17:57:41.733+00:00 I was managed to bring back to actual time but now all the client machines are ahead of time. Any resolutions to set them as the same time like AD server?

2021-12-02T13:32:01.107+00:00 Are you asking about PDC emulator or something else?
Some general info
- All domain members should use NT5DS domain time.
- Desktops and member servers sync with any domain controller.
- Domain controllers sync with PDC emulator (one per domain)
- PDC emulator in child domain can sync with any domain controller in parent domain.
- PDC emulator in parent domain syncs with either a hardware clock or possibly an external source.

2021-12-02T15:06:38.577+00:00 So you can see currently our clock is 75 seconds ahead of time now i execute few commands like w32 resync but still jumping ahead. If you could refer me any article or link on how to set AD time i would appreciate that just to you know i'd gone through https://blogs.technet.microsoft.com/nepapfe/2013/03/01/its-simple-time-configuration-in-active-directory/ site and did eveything still it doesn't change a thing.

2021-12-02T15:19:06.647+00:00 Ok, you can try setting a new time source or also reset the time service.
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 /configurationhttps://tf.nist.gov/tf-cgi/servers.cgi
