I have 1- PDC which has all role holds and 3 Additional DC.
PDC- Win 2008 R2 Ent
ADC- Win 2008 R2 Ent
ADC -DC01-Win2k12 R2
ADC-DC02-Win2k12 R2
I have External NTP Server. Our PDC - sync time from this NTP server.
PDC:- source of NTP is our NTP server. Configuration of PDC is..

2023-09-17T07:31:10.0566667+00:00 Error on ADC:
“NtpClient was unable to set a domain peer to use as a time source because of discovery error. NtpClient will try again in 3473457 minutes and double the reattempt interval thereafter. The error was: The entry is not found. (0x800706E1)”.

Anonymous2023-09-19T12:14:22.8166667+00:00 I posted above the commands but it sounds like you may have some other issues. What's in the event logs? Sysvol and netlogon shares present?

2023-09-17T12:51:05.5733333+00:00 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.
Might try resetting the problematic one.
w32tm /unregister net stop w32time w32tm /register net start w32time w32tm /config /syncfromflags:domhier /update net stop w32time net start w32timethen check
w32tm /query /source w32tm /query /configuration--please don't forget to close up the thread here by marking answer if the reply is helpful--

2023-09-19T03:30:53.7133333+00:00 I have performed same NTP settings on one of ADC. like
w32tm /config /manualpeerlist:"pool.ntp.org,0x1" /syncfromflags:manual /reliable:yes /update
w32tm /config /update
Restart-Service w32time
w32tm /resync /rediscover
w32tm /resync
ADC give perfect time from NTP. DCDIAG DcGetDcName(GOOD_TIME_SERVER_PREFERRED) call failed, error also resolved.
but on DC1 & DC2 same error. so pleaase guide is it right configuration which did on ADC
? If yes then i have to do for all Dc1- Dc2 ?
