No internet connection Vista 64bit

I have a really odd issue. I had a PC come in today with no connection to the internet. I've went through the usual issues checking IE settings, running cc cleaner and malware bytes. Removing the 7 different trialware AV suites that always seem to clog things up.

Now I am to a fairly clean installation, but I still get page cannot be displayed. What is odd is that I can ping the outside say or even by name. So the connection is there, but something else is going on. I can even open fileshares by name and IP.

At first my hunch was a DNS issue because if i try to NSLOOKUP anything it returns unknown server. However i cannot access a webserver device on my network by IP either (even though I can ping it).

It is consistent across browsers too, both Chrome and IE. Nothing odd in device manager either. I'm really stumped on this one.

    Also I've disabled the firewall thinking that may be it, but no luck there either.

    It sounds like your dns cache is corrupted. Try to flush it with command "ipconfig /flushdns" and see if it helps. Worst case scenerio is when your tcp stack may be damaged. You can try with command "netsh winsock reset" and reboot or download a tool called "winsock fix" to fix it and reboot.

    Here's one

    In an elevated command prompt (cmd), run the command below:

       ipconfig /flushdns

    Restart computer afterwards.

    I reread your post it does sound like your DNS is not working though. Try manually input it with Level3 or from OpenDNS

    Reseting the stack did it Dennis. Thanks!
