need some help in modifying Powershell script to get the NTP status for all domain controllers

Hi,

Can anyone here please assist me in how to get the NTP configuration setting for all domain controllers uisng Powershell below ?

$DomainControllers = Get-DomainController

Write-Verbose "Check Domain Time Configuration `r"
ForEach ($DC in $DomainControllers) { 
	$ADTimeCheck = w32tm /monitor /computers:$DC
	$ADTimeCheck1 = $ADTimeCheck -split ("ICMP: ")
	$ADTimeCheck2 = $ADTimeCheck1 -split ("NTP: ")
	$ADTimeCheck3 = $ADTimeCheck2 -split ("RefID: ")
	$ADTimeCheckICMP = $ADTimeCheck3[13]
	$ADTimeCheckNTP = $ADTimeCheck3[15]
	[array]$DomainNTPStatus += "$DC,$ADTimeCheckICMP,$ADTimeCheckNTP"
}

$DomainNTPStatus

Open in new window


because when I use the Powershell script above, it failed with no result.

Note: the Get-DomainController cmdlet is from the Exchange Server 2010 powershell.

Thanks in advance.

Corrected version of LearnCTX's.  But if you don't have the AD module you'll have to let us know.
Import-Module ActiveDirectory
$DomainControllers = Get-ADDomainController -Filter * | Select -expand Name

Write-Verbose "Check Domain Time Configuration `r"
ForEach ($DC in $DomainControllers) { 
	$ADTimeCheck = w32tm /monitor /computers:$DC
	$ADTimeCheck1 = $ADTimeCheck -split ("ICMP: ")
	$ADTimeCheck2 = $ADTimeCheck1 -split ("NTP: ")
	$ADTimeCheck3 = $ADTimeCheck2 -split ("RefID: ")
	$ADTimeCheckICMP = $ADTimeCheck3[13]
	$ADTimeCheckNTP = $ADTimeCheck3[15]
	[array]$DomainNTPStatus += "$DC,$ADTimeCheckICMP,$ADTimeCheckNTP"
}

Edit: Sorry I've just realised you're using Get-DomainController and not Get-ADDomainController. Why not use the AD cmdlet instead of the Exchange cmdlet? Surely the Exchange server would have this cmdlet available?

I've edited the below for Get-ADDomainController instead of Get-DomainController.

Import-Module ActiveDirectory
$DomainControllers = Get-ADDomainController -Filter *

Write-Verbose "Check Domain Time Configuration `r"
ForEach ($DC in $DomainControllers) { 
	$ADTimeCheck = w32tm /monitor /computers:$DC.Name
	$ADTimeCheck1 = $ADTimeCheck -split ("ICMP: ")
	$ADTimeCheck2 = $ADTimeCheck1 -split ("NTP: ")
	$ADTimeCheck3 = $ADTimeCheck2 -split ("RefID: ")
	$ADTimeCheckICMP = $ADTimeCheck3[13]
	$ADTimeCheckNTP = $ADTimeCheck3[15]
	[array]$DomainNTPStatus += "$DC.Name,$ADTimeCheckICMP,$ADTimeCheckNTP"
}

This is the value of the variable:

$ADTimeCheck

{Analyzing Microsoft.ActiveDirectory.Management.ADDomainController.Name (1 of 1)..., error WSAHOST_NOT_FOUND], ,  ,  , Microsoft.ActiveDirectory.Management.ADDomainController.Name [}

Do I have to run it from the Domain Controller or it can be executed from my laptop using the PowerGUI script editor ?

all of the hosts from the previous result are online and ping-able.

Even while it's a bit off topic ... such woes are one reason for me to avoid W32time whenever I can.

My recommendation:

Use a Windows port of the classic *ix NTP service on your servers. The status could be retrieved remote with a single command (ntpq -p <ip/name>) and the configuration is a very simple plaintext file. The NTP service software is free. Easy to install and configure, works like a charm and is stable as a rock. And it is nicer when it comes to one of the rare cases of troubleshooting.

See this article for the "How To".

The NTP service has a low ressource footprint, therefore the NTP functionality could be hooked onto existing machines or VM's like webservers, ftp servers, mailservers or database hosts - even in a DMZ - without visible performance impact.

If securtity is an issue, you might as well place radio controlled clock appliances into your LAN who serve time very reliable and precise.

You can run it on a workstation if it has RSAT tools installed so that the ActiveDirectory module is available.  Otherwise, it would have to be done from a domain controller (assuming Server 2008 R2 or newer).
