Hi Josiah,

Thank you so much for this script. Can you please also add another line to get the result via excel file instead of showing output within Powershell console itself? TIA

Thanks,
Bruce

Been a long time since I did Powershell stuff, but I think you could just modify the last line to $output | export-CSV or something like that.

Wow, didn't expect you to answer but you did. I will try that. Thank you so much!

I tried the last line to $output | export-csv "c:\dnssettings" but no results when I open the excel spreadsheet. Please let me know if you have any thoughts about it. Thanks for your help.

Managed to get it working with csv like this:

$AllServers=Get-ADComputer -Filter {OperatingSystem -Like "Windows Server*" -and Enabled -eq 'True'}
$Servers = ForEach ($Server in $AllServers){

$Result=Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "IPEnabled = 'True'" -Property DNSServerSearchOrder -ComputerName $Server.Name

New-Object -TypeName PSObject -Property @{
ComputerName = $Server.Name -join ','
DNSServerSearchOrder = $Result.DNSServerSearchOrder -join ','

} | Select-Object ComputerName,DNSServerSearchOrder | Export-Csv -Path C:\Temp\ServerDNSSettings2.csv -NoTypeInformation -Append
}
