Windows Server 2003 R2 SP2 will only allow me to browse google adobe and microsoft websites.

My windows 2003 R2 service pack 2 standard machine has developed a problem whereby i can only browse via Internet explorer or google chrome to www.google.com, www.microsoft.com and www.adobe.com. I have 40 machines on the network that can browse without any issues. I have tried resetting winsock and ip stack, the server works for about 30 minutes to all websites but then stops functioning again with the same initial problem. If i browse to a website on a non standard port this works, it seems ports 80, 443 and 8080 will not work except to the sites mentioned previously.
I have a piece of software on the server that was recently installed after this problem started that runs its own web page, even this does not work when it is hosted on the same machine on port 443.
I think if i were to disable and re-enable the network card the interent would work again for 15-30 minutes again, so i know it must be a software problem somewhere.
Any ideas would be greatly appreciated.

You have internet explorer enhanced security installed. This installs by default and doesn't allow you anywhere except MS and a few select sites. I usually just uninstall it.

Hi all, We are an IT company and have tried a lot of trouble shooting procedures aleady. This one has us stumped though . . .

It's not spyware or a virus, DNS is fine and we can ping websites fine. the silly thing is that we can ping say www.bbc.co.uk from command prompt but then we cant browse www.bbc.co.uk.
we've tried 3 different browsers but it's the same in all 3. it appears to be a network protocol issue. DNS is setup correctly and we've even changed to different external dns servers of & We get the same issue if we use public DNS servers and if we use the DNS servers assigned to us by our ISP.

We haven't tried moving the server connection to a different port in the switch so we'll give that a try today.

SOLVED, the customer had previously had a program called Spector 360 which was a web filtering program. It hadn't removed properly through add/remove programs and was still semi-active on the server.
Thanks all for advice
