Where szName matches the server name, and szMachine is (oddly enough) the machine address. For initial debugging, maybe try a raw IP address

My bet is that you'll need the blank security descriptor bit from above.

Does this mean that the pipe this way is also potentially accessible from the Internet?

That said, I wouldn't dream of using a named pipe for working over the internet - just simply because of how flaky the big bad world is. Dropped connections, lags, etc. And windows only, I'd think (for all I know, someone has done a bang up job of writing a unix clone).
