Detecting Whether the Remote Desktop Services Role Is Installed
You can use the Win32_ServerFeature WMI class to detect whether the Remote Desktop Services server role is installed.
The following C# example shows a method that returns True if the Remote Desktop Services server role is installed and running or false otherwise. Because the Win32_ServerFeature WMI class is only available beginning with Windows Server 2008, this code is not compatible with earlier versions of Windows.
static void Main(string[] args)
{
// 14 is the identifier of the Remote Desktop Services role.
HasServerFeatureById(14);
}
static bool HasServerFeatureById(UInt32 roleId)
{
try
{
ManagementClass serviceClass = new ManagementClass("Win32_ServerFeature");
foreach (ManagementObject feature in serviceClass.GetInstances())
{
if ((UInt32)feature["ID"] == roleId)
{
return true;
}
}
return false;
}
catch (ManagementException)
{
// The most likely cause of this is that this is being called from an
// operating system that is not a server operating system.
}
return false;
}
