I am at my wits end here.
I have a network of computers set up at my office. There are about a dozen computers being run altogether. The main ones being used on our floor are all newer Asus all in one models, and they run perfectly fine. There are a couple in the back that are quite old XP machines and they are running fine. But there are two Acer mini desktops with Windows 7 in the shop that are both having the exact same issue. It just started about a week ago and came completely out of nowhere.
These two computers can both send and receive email completely fine. They both list that their network connection is connected to the internet and both sending and receiving packets constantly. However, when I go to any browser, whether it's IE or Chrome or Firefox, and try and load SOME websites, those websites won't load. I can google things, I can go to Facebook, it's just some websites that completely refuse to load.
When I run the internet troubleshooter, it says that "Your Computer is correctly configured but the device or resource (DNS server) is not responding." Sometimes. Sometimes it shows that there are no issues and asks me what specific issue I'm having.
I'll explain our setup a bit. There is the main router/modem from our ISP, with the routing capabilities turned off so it's basically a modem. That runs to a 24 port wired linksys router, which then runs into the multiple computers plus one more switch that gets wired throughout the building. Both computers having the issue run through this last switch, but all the working computers also run through this switch.
I have a few devices set up with static IP's, but the rest are dynamic. In the Linksys router I've set the DNS to Google's because I found that it's actually faster than the default.
I've followed every Microsoft resource and every other resource I could find for troubleshooting. I've flushed the DNS, done the winsock and reset int or whatever. I've done it all. I've tried both static and dynamic IP's. I've tried starting in safe mode. I've both rebooted and factory reset the router and rebooted all the switches.
I just don't know what to do anymore. If it was just one computer then I would reinstall the OS. But all of our computers have the same antivirus, same network settings, same switch. These two computers have vastly different programs on them because they are used for vastly different things, so it isn't some rogue program.
Please help.
Quick Edit: I checked as well and the IP addresses are different on both machines so it isn't a conflict.
