Does that mean you are running the DCOM component from some client or running the native code from within VFP? Also, if you are running it as a DCOM and logged in as Admin, what is the impersonation set up for in DCOM?

Try stripping the code down to simple tasks like echoing "Hello World" or something equally simple. Then start adding lines back in. Debugging this kind of stuff is very difficult unfortunately. Best of luck, sorry I couldn't help more.
