Persistent RDP on Windows 7 Pro

I have a windows 7 station on the plant floor that makes an RDP connection to our Remote desktop server.  It automatically starts the app on boot and logs in, loading hte application needed on the station.  

the issue I wish to find a solution to at this point is having the session re-open if someone closes it down.  In other words.

Station Boots up, logs into Windows automatically, through GPO loads MSTSC.EXE C:\default.rdp
Default.rdp has saved credentials so it connects to the server and logs in automatically

IF someone closes the rdp session whether it is from logging out, or disconnecting or whatever other means, i was hoping there was a method of automatically reconnecting the session.

It can be another application that makes the RDP connection, or somethign that says if the RDP app closes, reboot the computer so that the rdp re-starts.

Any suggestions woudl be appreciated.
