We assume you have no firewall that might be getting in the way, and that you are hitting tomcat in a local browser, yes? (Forgive me for the stupid question but I just have to ask.) And, did you go with the default 8080 port configuration? Or did you change it to 80 (like I have done myself in the past)?
Have you check to see if the service has started in the Windows Service Manager? And if the service has started, have you looked inside the log files in tomcat-home/log? If there is a service error you will see it in one of these files.
