Having some odd internet issues

[Stewie]

I am not able to browse to any sites. my email will not send and receive, yet my internet connection is working. I received steam notification that a friend was playing and was able to chat in steam. Utorrent works.
When I open my browser I get "the network connection was reset.." error message
I use FF, I also tried IE = neither works
I am running win 7 64bit
I have cycled the power on the modem, tried disabling and re enabling my network connection, have turned off all firewalls and my trend micro, have tried different connections on my router.
The computer I am posting this on is connected to the same router and no issues.

It just seems email and web browsing do not work
I am at a loss. any help would be appreciated.

Sounds like you have a firewall blocking ports 80 (web) and 25 (mail). Try going to an https:// site, like a bank site and see if that goes through. Did you do anything where you changed the windows firewall settings? Do you have McAfee and your subscription is near expired (that has been known to bork network connections)?

One thing you may want to try is opening a cmd prompt as administrator and doing a winsock reset.

Go to the start menu.
Type 'CMD' in search.
Right click the little black icon and select run as administrator.
type in the following command: netsh winsock reset
It will then say you need to restart your machine. That command will rebuild your entire TCP stack.

Oh also, do you have IPv6 on? That sometimes causes wacky issues with Vista/MacOSX/Win7 connections.

One other thing to consider is if you have a hardware router it may be going bad.  Mine was doing similar things: some ports were just not working, sometimes websites would go through, sometimes they wouldn't until they eventually wouldn't 90% of the time.  My other half's computer was hit really hard long before I ever had a problem, regardless of which port we were plugged in to.  I replaced the router and the problems all went away.

Go to network properties.

Disable the network adapter.

Reenable it.

Edit: The actual specific adapter, not the connection, unless that's what you meant.

Check your DNS servers, for instance if you can get to http://66.102.7.106/ and not http://google.com your DNS is not working. In that case change them to:

208.67.222.222
208.67.220.220

And you're set.

After trying your suggestions and a few others, none of them seemed to work. It turns out that it was being cause by my Virus scanner.
Chimpy may have been right, although I an not 100% certain cause I just uninstalled Trend Micro.
After uninstalling Trend micro everything was working again.

Either way thanks for your suggestions!
