Hi 18584J

This may help The first line clears your DNS cache. The second line resets your TCP/IP stack.

From a command line

1. IPCONFIG /FLUSHDNS

2. NETSH INT IP RESET RESET.LOG

3. Reboot

Just run this in Windows 7 32bit and should run in 64bit

Veedaz! thanks for your help!

I was having similar problems.

Many websites wouldn't load properly (such as facebook not displaying any pictures) and others website would not load at all (such as cnn.com). If it did not load I would get the following errors:

In Firefox - "Firefox can't establish a connection to the server"

In Chrome - "Error 2 (net::ERR_FAILED): Unknown error."

Flushing the DNS, rebooting my router and rebooting the pc solved everything for me.
