Goto > START > RUN > type this CMD > click OK.
Now type "netsh int ip rese" and press ENTER.

This will reset you TCP/IP totally.

Then perform your ipconfig.

If that doesn't do it, then you probably have virus issues or spyware issues or both.

When checking for spyware, run Adaware. After Adaware has completed run Spybot. Running one may not find every spyware program you have, so it's best to run 2.

Hope that helps!
