NTP client configuration on Windows 2003 Server

[Igor Sovin]

Hi !

I want to set my Windows 2003 Server as NTP client.
NTP server is configured on HP-UX machine.
How to configure Windows machine to get time from the machine running HP-UX ?

[Igor Karasik]

Igor,
Try
net time /setsntp:

Also, check that W32time service (windows time) on windows 2003 is started

You can see
http://www.microsoft.com/technet/itsolutions/cits/interopmigration/unix/usecdirw/21wsdsu.mspx
as well

[Igor Sovin]

I did so.
It doesnt syncronize, although I see my hp-ux server in the output of

/querysntp

[Igor Karasik]

>>It doesnt syncronize

Any related errors in Windows event viewer ?
w32tm service started ?
w32tm /monitor output ?

[Igor Sovin]

w32tm started.

w32tm /monitor

Getting DC list for default domain...

Analyzing: 1 -- (0 of 2)

resolving referer 192.168.255.254 (1 of 2)...

resolving referer 192.168.255.254 (2 of 2)...

lyra.snos.ru *** PDC *** [10.1.32.1]:
ICMP: 6ms delay.
NTP: +0.0000000s offset from lyra.snos.ru
RefID: core2.mgmt.snos.ru [192.168.255.254]
leo.snos.ru [10.1.32.2]:
ICMP: 0ms delay.
NTP: +0.0004670s offset from lyra.snos.ru
RefID: core2.mgmt.snos.ru [192.168.255.254]

But the output doesnt contain the hp-ux server taht I want to syncronize with.


Last warnig in event Log was:

Event Type: Warning

Event Category: None
Event ID: 47

And when there is an error:

Event Type: Error

There are some values that you have to edit in the registry in order to use Unix as NTP server, please see:

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

Sync with the navy time server with "w32tm -s".

If you get a response that looks something like "RPC to local server returned 0x6b5", then it worked, but if you get "RPC to local server returned 0x0" then it did not, which usually happens if you run the command while the w32time service is running."

If you find a solution in this answer, please remember to thank with points.

Cheers.

Hi Ivan!
I think that microsoft note provided helped me to solve my problem, but /s option in w32tm doesnt work.
I cant check if there is a syncronization process between windows machine and HP-UX server.

[Ivan Ferreira]

You are right, the w32tm -s is for windows 2000, for 2003 is w32tm /resync.

If you stop and start the w32time service you should see and even entry in the system log like this:

The time provider NtpClient is currently receiving valid time data from server (ntp.m|0x0|192.168.0.1:123->192.168.0.2:123).

[Igor Sovin]

It looks like sycronization doesnt work, although I see IP address of Windows machine in "ntpq -p" of my hp-ux time server.

There are w32time errors in Windows Event log.

Event Type: Error
Event Source: W32Time
Event Category: None
Event ID: 34

Description:
The time service has detected that the system time needs to be changed by -7186 seconds. The time service will not change the system time by more than -3600 seconds. Verify that your time and time zone are correct, and that the time source judy.snos.ru (ntp.m|0x1|10.1.1.78:123->10.1.1.61:123) is working properly.

Finally I solved my problem.
According to error in Event Log I turned internal clock of Windows Server machine manualy and then did w32tm /resync. Now it works fine and i see informational message in System Log (..now receiving valid time data.. ) that Ivan told about.
Thanks guys!
