To debug remotley a few things have to occur:
You have to be a member of the debuggers group on the remote machine.
If you do not own the process that ASP.NET runs under you must also be in the Admin group on the remote machine.
The remote debugging components must be installed on the server.
The project has to have the debug symbols loaded into it. (By and large a system that is released for production has its debugger flags turned off)
Also, since this app is already compiled, I don't know of any way to step into the source code and take a look at it.
