Microsoft's Remote Desktop technology is Rocket Science. I have no idea how it works, but I've come to depend on it. Gone are those trips down to the server room to stand in the cold while installing an application. Gone are the days of bringing home the project on CD and having everything installed at home. I just VPN and connect to my machine at work. Over my Cox connection, it's like I'm sitting at my desk.
So when it doesn't work, it sucks. There's a bug in the client that causes everything to be REALLY SLOW on a second connection. Well, MS has a fix for this that will be released with XP SP2. But for now, a simple restart of your remote computer will do it. Problem is, it's not obvious how to restart your computer when connected remotely. You don't get the shutdown options. So, if this happens to you, open a command promt, and type the following:
tsshutdn /reboot
