How to disable NTP client on Windows Server 2008

  • 772

I configured a Windows Server 2008 machine to be an NTP client using some instructions I found elsewhere.

net stop w32time
w32tm /config /syncfromflags:manual /manualpeerlist:"0.pool.ntp.org, 1.pool.ntp.org, 2.pool.ntp.org"
w32tm /config /reliable:yes
net start w32time

But this is actually causing more problems than it's solving. I have a couple of client-server applications that complain bitterly when the system clock changes by even a fraction of a second. So I need to undo the changes I made.

What commands do I need to enter to revert the clock sync to its default settings of not syncing with anything? Do I need to change the /syncfromflags, /manualpeerlist, and/or /reliable settings?

  1. to unregister the timeservice run:

    W32tm /unregister

    To reset it to the defaults run

    W32tm /register

    ou might also consider increasing the LargePhaseOffset settings so that the only time it will resync is when the time is very far off (you'll still get the app complaint but at least it will be because time really was off by alot)

    See Windows Time Service Tools and Settings
