For many people, one simple yet frustrating problem is finding out which port Terminal Services is listening to for incoming connections.
The default is 3389, but people edit the default for security reasons (or sometimes merely out of curiosity), then can't remember whether they edited it or not. It matters, because if the clients aren't pointing to the right port when they attempt to connect, the connection will fail -- editing the port will affect future Remote Desktop Procotol packages, but not the ones you distributed before changing the port.
It also matters because no Terminal Services tools display or allow easy access to the listening port. (This may be because a terminal server can have more than one network card and, therefore, could conceivably be listening on two ports that would need to be configured separately. But this lack of easy access to the listening port is still inconvenient.)
Rather than walking around to each terminal server, or even opening the Registry Editor for each terminal server, you can write a script to check the value and display it in decimal (which for most people is easier to read than hex). To work properly, our script needs to read a Registry key; convert the value of that key from hex to decimal; and record the value of the key in the Event Log.
