I got a strange problem, One of my clients keeps ending up in this mess. It seems that port 80 constantly get blocked and I can’t figure out how. Everyother port including port 443 works fine. he did this to 2 differnet PC now and the only way to fix it is blow away his profile. He says that he did not install any software or do any changes to the pc except go to his web sites.
OS is – WinXp Home SP2 ( but he did the same thing on Win2000 Pro SP4 )
I’ve verified that there are no firewalls running Including the WinXp firewall, Antivirus is disabled, antispyware is disabled, no VPN software is running.
I’ve done the following steps to try to rectify the situations
reinstalled nic ( Wireless and wired )
reinstalled TCP/IP
re registered DLL files
verified that the ports are not blocked by the os
verified that the HW firewall was not blocking the port
Host file is normal
routes seem normal
I can ping a web site via name or IP. Web sites starts to load and then times out
Network is as follows
Peer to Peer via an Motorola Wifi Router, yes on DHCP, Tried on DSL and Cable connections both results are the same. Connecting and transfering files is not a problem.
Ran a spyware/ virus check and all came up good. Yet a different profile on the same pc has no problems access in the web.
No registry problems found. user is an administrator of the local box
What can force a web page to time out??, When i uncheck Show friendly HTTP error messages, I get the following error
Request timeout
The server timed out waiting for the client request.
When show friendly http error messages is check the error message is
The page is unavailable
HTTP Error 408/409 – Not acceptable / Resource Conflict
Internet explorer
Any help would be appreciated
