Powershell to check Remote desktop with the latest feature enabled or not ?

Hi People,

Is there any way to test if Remote Desktop is available in a list of server ?

I'm in the process of filtering and searching through hundreds of Windows Server VM which could be affected with this issue: http://technet.microsoft.com/en-us/security/bulletin/ms12-020

so If anyone can come up with powershell script to identify which RDP version or feature is installed (with NLA or not) that'd be great.

Thanks.

Hi ,
This will give you what you want except the NLA information

 $servers = get-content servers.txt
 $results = @()
 

 ForEach ($server in $servers)
{
#  get the TS Setting object for current server
 $result = @()
 $result = "" | select ServerName, RDPenabled, Logons, LicenseType
 $ts = get-WMIObject Win32_TerminalServiceSetting  -computername $server -Namespace ROOT\CIMV2\TerminalServices
 $result.ServerName  = $ts.ServerName
 $result.RDPenabled  = $ts.AllowTSConnections
 $result.Logons      = $ts.Logons
 $result.LicenseType = $ts.LicensingType
 $results +=  $result
}

$results

Open in new window

Can you confirm which version of powershell you are using as there may be a way of using remote registry call to find out the NLa info.

Regards
Joe

ok, I've just found this URL: http://blogs.technet.com/b/jamesone/archive/2009/01/31/checking-and-enabling-remote-desktop-with-powershell.aspx

which tells you about the type of RDP connection, so how do I incorporate that into the script above that you mention ?

Function Get-RemoteDesktopConfig {

if ((Get-ItemProperty -Path 'HKLM:\System\CurrentControlSet\Control\Terminal Server').fDenyTSConnections -eq 1)
    {"Connections not allowed"}
 elseif ((Get-ItemProperty -Path 'HKLM:\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp').UserAuthentication -eq 1)
    {"Only Secure Connections allowed"} 
 else     
 	{"All Connections allowed"}

}

Hi

The problem you may be having is that the format of servers.txt i have attached an example with localhost in it twice.

sorry for the delay in replying, let me know how you get on,

Joe
