Windows 7: Configure Windows 7 client to sync with more than 1 NTP Servers

Configure Windows 7 client to sync with more than 1 NTP Servers

Hi

In my network, I have got 200+ Windows 7 Pro 64bit clients running in WORKGROUP setup. They are not part of any domain network.

We have got 3 external NTP Servers available to sync the Windows7 clients with the latest and updated time. I am not sure how to configure Windows 7 clients to talk to these NTP servers(Primary, Secondary, and Tertiary).

I would greatly appreciate any of your help in getting it configured to work.

Regards

Hi,

Welcome to 7 forums.

To configure NTP servers there appears to be no GUI. But you can use the W32TM CLI. W32TM /? will give you a list of options. Use the /config command to configure your ntp peers list.

pool.ntp.org: the internet cluster of ntp servers has a pool of servers that you can use.

This is an example I found on Technet (Credit tekcert.com | Business. Technology. Certifications.)

w32tm /config /syncfromflags:manual /manualpeerlist:"10.0.10.20,01 0.us.pool.ntp .org,01 time.apple.com,01 " /update /reliable:yes

More information about the W32TM command can be found here..

Thanks Tanya for the response.

What does the 0x1 before the second and third NTP Server that you have mentioned? Does it mean they are the secondary servers?

Near as I can tell, it means the server is a DNS name. When you specify the server by IP address you omit 0x1.

Just had a hunt through my history from when I set this up a couple of years ago, and found another site that might explain things some more...

I'm not sure about how to use multiple NTP servers but it appears as if some registry adjustments are required.
