Slow program usage over mapped network drive

I have 4 computers and 2 printers connected to a linksys workgroup switch and a linksys router. All 4 of these computers use a mapped drive to access a program from a server specifically for sharing this program. Another computer from a different state connects to the server remotely to run the program and it is blazing fast. The other four computers lock up when trying to print and perform other basic functions. I have tried connecting to the server remotely from the local computers and it works perfectly. Obviously it is the mapped drive that is bogging down the computer. At most only 3 of the computers run the program. The terminal server is a dual 2.8 ghz xeon, it's perfectly capable. Would it be possible for three users to run the program at the same time from the server while connected via the RDP? Could I create a link to start a remote desktop connection to the terminal server and load the program without the users having to make more than one click?

 

Yes, this should be entirely possible, i run something similar to this set up with my game servers

 

Awesome! How would I go about creating that shortcut I referred to?

 

for that you will have to play with login scripts

good luck!
