A process can't debug itself since the "ZwDebugActiveProcess" function returns ERROR_ACCESS_DENIED if its first parameter is a handle to self.

Alternatively, you can spawn a helper process to do that.

batman2xp, are you referring to a process which runs another copy of itself and debugs *that*?  if so, then you are too late.  what you need is to intercept the process creation and zero the debug port so that you can attach your own debugger.
