Firewall Security: HTTP Forbidden Error 403

Message: I was having issues with the firewalls and security, and conflicts with my norton security I disabled the Vista and ended up with everything disabled, I could not get on the internet or my email, I had my server here, thinking it was a issue with the address being diabled and the dsl modem reset, They are not too fimilar with Vista and unable to connect, We continually get the HTTP 403 forbidden error, I was able to get the email to work, the comupter is connected to the interent and no problems when I ran diagnosis on it, so my email works ,

I went into the admin. tools , services and almost all where disabled, so i went in clicked them to automatic, enabling them, its to click on something to allow inbound/outbound security, but, I dont know what ones to run start, stop etc. I need information as to what to click or unclick, what to allow or not allow to access the internet, So what I am saying is the internet connection is up and working, I am able to go into my email and send and recieve, but, when I go to my internet browser, click to go, it says HTTP forbidden error 403, you are connected to the internet but unable to view this page
