How to debug a program spawned by another program?

[jonwil]

ok, sounds like I need to get origin.exe into the debugger, find a way to get it to launch originclientservice.exe suspended, get THAT into the debugger then find a way to get that to launch renegadelauncher.exe suspended and then I can get THAT into the debugger in order to find out what it does (assuming I can locate the correct place to plant a breakpoint to hit the OEP after the copy protection has done its thing)
