I have two computers connected to the same router. 1 is able to navigate to any website with no problem. The 2nd computer is unable to navigate to almost any website except google.com, Windows Update website, and a handful of others. All other websites (which we used to be able to navigate to without problem) will not load.

I am totally perplexed by this. It just happened yesterday. I have reset the router several times, but still no joy.

any help is greatly appreciated.
