You all People, did you try to understand one thing here.. if you allow IIS to run your exe file... anybody can hack into your machines....Now, there are few ways to accomplish this task. First one i can think about is create a component using C#/
VB class library which executes the .exe file. Call this component in the asp.net page. That way you can avoid much of hassle... Ofcourse there are security issue there also...but i will leave that to you! :P
