There are two computers on our network that "suddenly" stopped connecting to the internet according to the user. All the other computers are running just fine. Neither Google Chrome or IE can connect to any webpage. However, both computers can access anything else on the network and also randomly change from showing "internet access" to "no internet access" in the network center. Also, even though no webpages can be loaded, the computer is still apparently connected to the internet because they can be accessed remotely through Team Viewer from outside the network over the internet.


System Restore helped with nothing and I tried to install Ad-Aware to do a scan, but the installation fails because it cannot connect to the internet.


The machines are running Windows 7 Professional x64 bit.


It was the same user who was on both machines when they went down, and based on the browsing history, it looks like this could possibly be related to some sort of malware/spyware as opposed to coincidental hardware issues.


**Edit** - I did check the Ethernet cables with my laptop and have no issues connecting to the internet from the laptop.

I hope your company's security infrastructure's intact and strong, so that whatever is troubling these two computers [via downloads and/or internet installs] will not travel to other computers within the company.  Could the company-wide security systems also be "interrupting" this particular user's "interneting?"
