This does not work. I tried this before posting this question.

Thanks Justin. I ran the script and found it running, but everytime it shows up as the Nic is set to Auto Negotiation.
I tried changing the registry from 0 to 4, but still it shows Auto Negotiation.

Its ok. I figured it out. Thanks a lot.
The script works great. This is what I was looking for.

Exactly what I was looking for. Thanks Justin.

I changed a bit, it should display the registry *SpeedDuplex numbers and see if that is correct, and remember your registry need to be closed after you changed it on the remote server.

$servers = Get-ADComputer -Filter {OperatingSystem -like "*2012*"} -Properties *
foreach ($server in $servers)
{
$Servername = $Server.name

$registry = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine, $serverName)
$baseKey = $registry.OpenSubKey(“SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}”)
$Subkey = $basekey.GetSubKeyNames()  
foreach ($Sub in $Subkey)
{
if ($sub -like "0*")
{
$Result = $baseKey.OpenSubkey($sub).GetValue("*SpeedDuplex") 

Write-Host $result "of" $($baseKey.OpenSubkey($sub).GetValue("DriverDesc")) "on" $Servername

}
}
}
