In order to get help, you'll need to better explain what you're trying to do and why. Typically, you do not run Fiddler on a web server, you run it on a client that accesses that server. (It is possible
to run it on the server, but it is not generally useful
to do so). What is making requests to Google (code on the server? A client's browser? something else?) and how specifically do you want those requests to be blocked (TCP FIN, TCP RST, HTTP/5xx response, something else)?
