check user account control setting for multiple servers

$servers="DEN-DC-01", "DEN-GW-01", "DEN-SRV-01","DEN-SRV-02","FTC-CL1-01"
Function get-UserAccountControl ($server)
{
[string]$RegPath = "Software\Microsoft\Windows\CurrentVersion\Policies\System"
[string]$RegValue = "EnableLUA"
$OpenRegistry = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine,$server)
$subKey = $OpenRegistry.OpenSubKey($RegPath,$false)
$UAC = ($Subkey.GetValue($RegValue) -eq 1)
 if ($uac -eq 1 )
 {
  return( " uac is enabled")
 }
 else
 {
  return (" uac is disabled")
 }
}
foreach ($srv in $servers)
{
	write-host "The server is $srv"
	$useraccount= get-UserAccountControl($srv)
	write-output $useraccount
}

When i run the above script, i get the UAC control enables for all the servers though it is disabled in most of the server.
Can someone help?
