I am running Windows Vista. Sometimes my browsers will abruptly stop displaying webpages. The error on Mozilla says- Unable to Connect, on Safari - Winsock Error 10013
I am able to ping, my DNS servers are working (so its not a connectivity problem- other computers on the same network are able to access the internet), and the hosts file is in order. When I reboot, all works well for sometime before this problem strikes again.
The error reported by Safari seemed to suggest a WinSock problem. So I even re-installed TCP/IP by cleaning up the registry entries for WinSock and Winsock2 and putting in fresh copies. The problem still persists.
I used a port scanner program to see what apps are running on them, and several report- "An attempt was made to access a socket in a way forbidden by its access permissions".
My checks with ESET A/V and Spybot suggest that the system is clean.
How can I troubleshoot?
Thanks for your help, this problem is really irritating me.
