The Remote Desktop Command MSTSC.EXE
If you want to start Remote Desktop from a command line or run prompt you want to use the Remote Desktop Command MSTSC or MSTSC.EXE which starts the Microsoft Remote Desktop client. You can find the remote desktop client under the accessories folder in all programs however it is much faster to start Remote Desktop with the command mstsc. I just click start and if on Windows XP I type mstsc and hit enter or ok. On Windows Vista or Windows 7 you just click the start button and type mstsc in the run blank and hit enter to start Remote Desktop.
