Spyware/Trojan Attack -> No DNS service

[Vizco]

My kids' computer (running 98SE) was massively infested just before Christmas.

The result, even after running HijackThis, SpyBotS&D, AdAware, and CWShredder, was a machine that can ping other machines, but cannot resolve addresses. (www.yahoo.com, for example).

I can map network drives from it on other machines on the LAN, and vice versa, so the net basically works. The machine uses DHCP, and it has a valid license on the router. Winipcfg shows it as trying to use the DNS servers provided by DHCP.

I have tried repairing and reinstalling 98SE and IE 5.5.

No dice. HJT log available if needed, it's pretty clean looking to me though.

Thanks for any help. I'm stumped.
