This has got to be one of the coolest (geek) things I’ve found all year. If you have two monitors and want to emulate multimon environment from a remote server, you can do it by running the following from Start - Run menu.
mstsc /w:2560 /h:1024 /v:servername
These options aren’t available if you open the standard Remote Desktop dialog, but you can get around it by using the parameters.
Note: The only kicker is that if you try to maximize a window of a given application (i.e., Internet Explorer), it will maximize to both screens. To set the default, open IE and position where you want it to be. Then hold down the ALT key and close it. The next time you open IE, it will open it in the same place.
