Some time ago I was asked to write a PowerShell script to do an inventory of the time server (NTP) configuration on clients.
Today I was asked the same, so I grabbed my old script, expanded it a little and here you go 🙂

You might want to check the w32tm utility:
w32tm /query /computer:pc1 /source
That output is tricky to put into a CSV and do some selecting/sorting on it, that’s why we’v used the script I posted 🙂
Thanks for the article. Can we run it against a list of servers in a text file?
Hi Weiyentan,
Sure, you can call it like so:
Get-TimeServer -ComputerName (get-content C:\Users\Jeff\Desktop\123.txt)
Jeff.
Thanks for the script, made some adjustments to accept pipeline input but its working great
Hi Marco,
Happy to read you found it useful 🙂
Jeff.
Hi Jeff,
I am aa little confused how you use Get-TimeServer -ComputerName (get-content C:\Users\Jeff\Desktop\123.txt) which is what i am trying to do with this script are you able to give more detail? I am not sure how I use this script
