Time Sync help

js-bts · 2021-04-08T13:30:58.000Z

Hi,

We have a client who has some machines which are still trying to sync with a DC (I believe this has been decommissioned) and they’d like their machines to stop trying to sync their time with this, and we’d like to do this via Powershell.

What’s the best approach for this? Ideally, I’d like to set their time to sync with time.windows.com.

Please let me know if you need any more information - and thank you in advance!

EDIT:
Thanks for the responses - not sure if it’s perfect, but the below seems to have worked a charm:

Stop-Service W32Time
Start-Service W32Time

w32tm /config /manualpeerlist:time.windows.com /syncfromflags:manual /reliable:yes /update

Set-ItemProperty -path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers' -Name '(Default)' -Value '1'

w32tm /resync

What have you tried? where are you stuck?

Most commands will be just same old w32tm / whatever you want to use.
You don’t want to sync from the new Domain Controller?

You can specify a custom NTP server in the reg key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers

If you post code, please use the ‘Insert Code’ button. Please and thank you!

Hi, and welcome to the PowerShell forum! Don’t apologize for being a “noob” or “newbie” or “n00b.” There’s just no need – nobody will think you’re stupid, and the forums are all about asking questions. Just ask! Use a descriptive subject. Don't say "Need help" or "PowerShell Help", actually summarize what the problem is. It helps the rest of us keep track of which problem is which. Don’t post massive scripts. We’re all volunteers and we don’t have time to read all that, nor will we copy, past…

simply run command

w32tm /config /manualpeerlist:"time.windows.com,0x1" /syncfromflags:manual /reliable:yes /update
w32tm /config /update
net stop w32time && net start w32time
w32tm /resync

also, see if any GPO is pointing to old DC

Thanks both for your responses - they’ve helped put me in the right direction. Seems I’ve managed to work out a solution that looks to have ticked all the boxes (pending some further testing) - I’ve added this to my original post.
