My friend's ipconfig says "Unable to query host name. Contact M$ blah blah blah" when trying to pull up an i.p.

How can I help him get across this problem?

It all happened because one of my friends other friend had accidentally tripped over the power surge and accidentally pulled it out of the power socket, disconnecting PC - Modem - Printer etc. When he plugged everything back in and attempted to continue roaming the net, it wouldn't allow him, so I try to ipconfig/ all, and then we got msg about "Unable to query host name".

I heard of Winsock tool and various other methods that I have saved as possible solutions.

Hell, even some modems have administrative options, try to log in there.

An example is that generally these settings are found at http://192.168.1.1 but some routers don't.

If you still don't have internet call your ISP and bitch to them you broke it being stupid, I bet that they will love you guys.

And so what I want to do is delete the newer tcpip file and rename the old one from 'tcpip.sys original' to just 'tcpip.sys'.  Once that is completed, I uninstalled the NIC driver, rebooted the pc and reinstalled the NIC driver and now, he's back online!!!

Thanks for the help
