Windoze unable to resolve dns names

[The PIT]

I've seen a few computers do this. I've solved in the past but I cannot remember how I did it.
Basically you can ping ip address's but not the host name so IE won't work etc. Any ideas.

I have also seen thgis wierd behauvier....

Only thing that cured it was a reinstall.....

Watch out for proggies that mess with DNS. I have seen the new.net program which is installed with kazaa go screwy and cause this behaviour. Check if it is in your add/remove programs list and uninstall it. I have run into this behavior many times and it can sometimes be a battle to resolve.

check your c:\windows\system32\drivers\etc\hosts

it should contain just one line

127.0.0.1 localhost

Yeh I was wondering about a corrupt host file.
Couldn't see any strange programs floating around. Last time someone had zonealarm installed. The uninstaller removed it from uninstall memu but left running in the background. Deleting the directory solved the problem. However nothing like zonealarm was installe deither.

I have used LSPFix (linked on http://www.geocities.com/Pentagon/Qu...newdotnet.html) before to fix a simillar problem.

Edit: better link: http://www.cexx.org/lspfix.htm
Good Luck.

You using NTL cable?
If so, that means CableModem MAC address is not properly registered (or the NIC MAC address).

You might want to have a look.

And if you are using NTL, try pinging 194.168.4.100 and 194.168.8.100 they are the DNS servers, see if they response.
Don't use DHCP, config DNS servers as static setting.

Hope this helps.

The machines in question were both dailup networking to our University. The kid hasn't brought the machine back so I'm presuming uninstalling and re-installing the dialup networking has cured it.
