Solve : Cannot connect to one specific website?

1.	Solve : Cannot connect to one specific website?
Answer» I am having a very frustrating problem with accessing a particular website. The problem: one single computer on my network cannot access this website, while every other computer/device on the same network can reach the site just fine. The computer that cannot reach the site is running Windows 7 Ultimate 64 bit. - "The connection has timed out. The server at www.ee.hawaii.edu is taking too long to respond." - Pings to the site are successful, but no browser can open the site (I assume this rules out a DNS issue, as pinging RESOLVES the IP address of the site) - Even trying to access the site using its IP instead does not work - I have tried IPCONFIG /flushdns command, as well as other netsh reset commands - If I boot off a gentoo linux livedvd, I can reach the site fine. It is just from this windows installation I cannot reach the site - Other computers connected via ethernet (static ip or dhcp assigned) to the same main router can reach the site, as well as laptops/phones connected via wifi/dhcp - I do not have windows firewall enabled at the moment, nor any other firewall software installed - I only have MSE antivirus actively enabled, but have disabled this and still has no effect - I have boot into safe mode with networking, and still cannot reach the site - I have run virus/other scans using MSE, malwarebytes, superantispyware, ESET online scan. Nothing of significance has been found, and am still having the problem - Windows hosts file is clean and in tact, no entries besides the localhost entry - The browser I use is irrelevant, I cannot reach the site with firefox, IE, chrome - Have cleared numerous cache/temps, even with CCleaner - I can browse any other site just fine - I have been able to reach the site from this computer with current OS in the past Anyone have any ideas?

It has to do with some settings in windows.
Try this: Make a new user account with normal PRIVILEGES. Log into that new user and see if the behavior is the same.

It may be a 'parental control' that blocks the site. Try using a proxy to see if that makes a difference. But hard to imagine that anybody would block http://www.ee.hawaii.edu/ for any reason.

Do you mean something in the linksys router I am using? I have tried reflashing the firmware back to a clean original state, would this have done as you stated? The problem still persists.

Time to review the facts.
It used to be OK.
The problem is only with
www.ee.hawaii.edu
But what about a base that site? Like http://hawaii.edu
Other PCs on the network do not have a problem
Same PC with Linux does not have the problem
Same PC has the problem direct from modem.

It is NOT in the hosts file.
