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
. 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.
