2008 r2 server cannot connect to internet using port 80
Posted on 2012-12-21
I have a 2008 r2 server, if I try browse local websites on port 80 they show fine, if I try browse remote websites they fail with "Internet Explorer cannot display the webpage". If you try the diagnostic it cant find anything wrong.
1.I have already stoppped the windows firewall without any success
2.I can browse websites on port 44 no issue.
3.There is no gpo policies etc configured
4.This is a straight 2008 web server with web role installed
5.I can do dns lokups and I can ping these sites fine, I just cannot brose to them on port 80 from the server.
6.
it seems as if only port 80 outbound connections are blocked.

Have you tried another browser (Firefox, Opera, Chrome, anything) to be sure the problem is repeatable? That would help identify the problem as software or network related.
Do other computers behind the same router/firewall have similar browsing issues? This would help us identify if the network problem is internal to this system or a problem with the router/firewall.

Are you running antivirus software? Disable it and verify results. There have been many, many reports of AV or Windows updates not playing nicely together on occasion.
Install FF/Chrome and try the same sites. Success/failure?
Is this on a domain?
Do you have a proxy set on IE?

Is this the only server/computer that has an issue on the site?
What Anti virus software is installed? does it also have security software installed?
Does the server go via a proxy on the network?
SHOULD the server go via a proxy on the network and doesnt?
Is there a hardware firewall between the server and the internet that blocks port 80?
Can you browse HTTPS sites on port 443?
