    Hello,

    I'm trying to get a registry value for a group of computers out of Active Directory. Below is the script I had in mind, but that keeps failing. Can anyone give me an idea of how to accomplish this? Thanks

    get-adcomputer -filter {name -like "us*"} | select dnshostname | Get-ItemProperty -path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic
    es\W32Time\Parameters -name "ntpserver"

    What is the error message you are receiving?

    Based on this post Get-ItemProperty I think that command is ran on localy on the machine, so you can modify your script based off thier suggestions

    The problem is Get-ItemProperty is not capable of querying a remote registry.  You must use the invoke-command cmdlet to run it against a remote machine.

    Thanks for the suggestion.

    Can you give me an idea of what that command would look like?

    Give this a try, in order for it to work PSRemoting must be enalbed on the machines you are trying this on

    Import-Module ActiveDirectory

get-adcomputer -filter {name -like "us*"}  | select -expandproperty dnshostname | ForEach-Object {
	Invoke-Command -computername $_ -ScriptBlock { Get-ItemProperty -path HKLM:\SYSTEM\CurrentControlSet\Services\W32Time\Parameters -name "ntpserver" }
}

    My preference is to skip invoke-command and do it like this:

    $SRVS = get-adcomputer -filter {name -like "us*"} | select dnshostname

    foreach ($SRV in $SRVS) {
    $REG = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $SRV.name)
    $REGKEY = $REG.OpenSubKey("SYSTEM\CurrentControlSet\Services\W32Time\Parameters")
    $NTPSRV = $REGKEY.GetValue("NTPSERVER")
    }

    Thanks for the suggestion. I'm not sure what to expect with this. I just ran it but nothing returned. No errors. How can I get the output of this?

    Thanks,

    Scott

    You'll have to call the $NTPSRV variable (which I didn't do in the code above).  Everyone has their own preference on how they want the output but here are some quick examples: 

    If you just want to write the output to console, add this to the end of the foreach loop:

    "$($SRV): $($NTPSRV)"

    Or you can add this instead (or in additon to if you want both) to save the results in a CSV file (I delimited with ";" since the registry key value contains commas):

    "$($SRV);$($NTPSRV)" | Out-File SRVNTP.CSV -append

    I'd use Shay Levy's Remote Registry PowerShell Module
