I am using another computer with the Remote Desktop connection all set up and running, I terminated the process and ptute, gone.. no more connection... This file is fine in that sence, but if you didn't have Remote Desktop Enabled and setup and seen this running then I would have that Red Flag waiving high, someone could be using your computer, ONLY if you didn't set this up to begin with... My oppinion. But most cases It would only allow one connection to the Remote Desktop's computer at a time that I believe, whenever another user would try to log on, then a msg would popup if ok to logon

It's the Remote Desktop Client. You use it to connect to another computer's remote desktop.
I love that application - helps me with my research
Client's computer has mstsc.exe setup to run at startup. Points to %USER%\Application Data\Microsoft\Windows. Obvious fake. If this file is found anywhere but %windows%\System32, it should be considered very dangerous.

I use mstsc on a daily basis at work to remotely work on computers. It is a core Microsoft application for remote connections. MSTSC - Microsoft Terminal Services Client. It is a useful tool when used properly. When you log into a remote computer with mstsc you must have a valid Username and Password for the computer that you are logging into, also it will log off anyone who is logged into that computer with a prompt. Therefore if you have your computer protected with password required accounts it should not be a concern that anyone can just log into your computer with mstsc.

mstsc.exe provides access to terminal server’s functions using the commandline (dos prompt)
It showed up on my desktop, with a filesize of 510KB. Trend Micro's HouseCall program flaged it as a trojan. I certainly don't remember downloading it.
Essential for me to monitor systems on a SERVER FARM
I use ti every day to remotely access workstations & servers. I like it better than pcAnywhere. Simple but essential for work. Not essential for a home computer.
