I have a Vista workstation at work with 3 monitors. At home I have a laptop running XP. I commonly remote desktop into work and some of my programs will be running and visible in the task bar (e.g. Outlook, MySQL Administrator, etc...) but the actual window of the program will still be on my left or right monitor at work. So at home, it is not visible.

With a program like Outlook, it is an easy fix.
- Right Click the program in the task bar.
- Select Move.
- Use the left or right arrow key to move the running program so that it is visible in the remote desktop session.

By default in Windows Server 2003, you can be logged in via Remote Desktop (formerly known as Terminal Services or "TS" if you're "really cool.") up to 2 times. Basically, you can login as administrator or other account that belongs to the Remote Desktop Users group 2 times simultaneously without additional licenses.
