How can I check if my time sync is correct?

  • 772

I have updated a W2K3 settings according to the steps shown here:

http://support.microsoft.com/kb/816042#LetMeFixItMyselfAlways2

The peers list I use is:

0.asia.pool.ntp.org,0x1 1.asia.pool.ntp.org,0x1 2.asia.pool.ntp.org,0x1 3.asia.pool.ntp.org,0x1

I did a 

net stop w32time && net start w32time

to restart the service.

How do I check the settings? How do I know it's working?

When I try the following:

w32tm /monitor

The response I get looks like the time sync goes to the local computer (the DC) 

C:\Documents and Settings\Administrator>w32tm /monitor
    OptiDC.opti *** PDC *** [192.168.0.2]:
    ICMP: 0ms delay.
    NTP: +0.0000000s offset from OptiDC.opti
    RefID: 'LOCL' [76.79.67.76]
  • is that what the answer should be?
  • Shouldn't I see something that has one of the NTP servers from the peers list?
domain-controller time-synchronization w32time

    You can use w32tm and provide the names of the computers it should contact, something like 

    w32tm /monitor /computers:0.asia.pool.ntp.org,1.asia.pool.ntp.org 
Analyzing:delayoffset from local clock
(unknown)Stratum: 2
delayoffset from local clock
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.
