time.windows.com seems to be 3 minutes off with other NTP server

Hi,

I have my PDC emulator DC getting the time from time.windows.com.

I have been looking the time at other NTP like NIST at they seem to be 3 minutes ahead from time.windows.com

Is there any way to get the real time from time.windows.com? Going to their site and getting the real time displayed there?

I have fixed my problem as follows:

Ran the command w32tm /configure /manualpeerlist:"time.windows.com" /syncfromflags:manual /reliable:yes /update

We changed the setting from NT5DS to NTP under  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type.

Changed time in seconds to 900 under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient\SpecialPollInterval

Changed time in seconds to 1800 under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\MaxPosPhaseCorrection

Changed time in seconds to 1800 under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\MaxNegPhaseCorrection

It also took some time for the time to get sync

The client machine can sync time from any of the domain controllers. It’s not necessary that it will be the PDC one. So the machine on which we are seeing the difference of few seconds might be getting sync from the other DCs that weren't in sync with PDC yet.


Here are articles that I have used.

You dont have to use the M$ time servers. There are others that are Stratum 2 and 1 military grade that you can use that are public.

From the PDC I am running the following command - which says that my DC is going 3 minutes faster than time.windows.com

How do I fix this?

C:\Users\administrator.SYRACUSE>w32tm /monitor /computers:time.windows.com
time.windows.com[65.55.59.60:123]:
    ICMP: error IP_REQ_TIMED_OUT - no response in 1000ms
    NTP: +191.3552280s offset from local clock
        RefID: time.nist.gov [192.43.244.18]
        Stratum: 2

Warning:
Reverse name resolution is best effort. It may not be
correct since RefID field in time packets differs across
NTP implementations and may not be using IP addresses.
