Windows 7 , No internet Access but network connected

Hi,

One of our users started having problems to access the internet, although she has network connection. The IP was supplied by DHCP, I tested with a static IP and for a day or two, it worked fine, now we are back to square zero, without any internet access. The networking config is OK, I am able to ping, nslookup various websites, but cannot access them with any browser (IE / CHROME), by name and by ip.
Any hint would be very much appreciated.

Regards,

Run TCP/IP Reset and that will probably fix the issue.

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache

Restart and test.

You might also look at the Internet Explorer proxy settings.
If you do not use a proxy server then "Automatically detect settings" should be disabled.
If you have any firewall software installed or have the Windows Firewall enabled then you might try to temporary disable this firewall.

Thanks Both,
John, I followed your instructions and my user was able to access the internet for  few hours, then we came back to square zero : No more access, I used a number of antivirus/malwares to clean up the computer, again we were able to access the internet for a couple of hours, then no more access. Zalazar, I checked all these, but no results.

Any other hint would be very much appreciated.

Regards.

No more access, I used a number of antivirus/malwares to clean up the computer  <-- and again it stops. This means the computer has been severed compromised by viruses. Since you tried so many A/V steps/tools, the next step (for certain results) is to back up the computer, delete all partitions (because root kit viruses stick through formatting), format and install Windows fresh.
