We have two DCs on windows server 2008R2, DC1 and DC2.
DC1 is a PDC emulator and DC2 only has infrastructure master role.
I recently configured externl NTP on DC1 without any issues. but when I run command on domain PCs and find the they are syncing with DC2 instead of DC1
DC2 is syncing from DC1
On a domain PC
c:\w32tm /query /status
Leap Indicator: 0(no warning)
Stratum: 5 (secondary reference - syncd by (S)NTP)
Precision: -6 (15.625ms per tick)
Root Delay: 0.2587585s
Root Dispersion: 0.2337305s
ReferenceId: 0x0A050128 (source IP: 10.5.1.40)
Last Successful Sync Time: 27/07/2016 1:40:40 PM
Poll Interval: 14 (16384s)
C:\Users\administrator.domain>w32tm /query /source
C:\Users\administrator.domain>W32tm /query /source
My questions are
1. Are all domain controllers can be a NTP server?
2. If DC2 is offline, will other PC automatically to sync with DC1?
3. How can I change domain PCs to sync with DC1?
