One computer on LAN is unable to connect to Internet sites. LAN connects to Internet through a router, other computers have no problem.
Other computers on LAN are acessible through MS Windows Network. I can ping IP's outside the network, but not URL's - "...could not find host..." Obviously can't connect to a URL with browser, attempts to connect with IP (gateway router or external IP) fails:
- Opera: "Illegal address" reported.
- Netscape: Nothing at all happens.
_ IE: Familiar "page not found" page.
Disabling Windows Firewall has no impact.
I've never run into this behavior, and hope someone here will recognize it! Obviously the laptop isn't getting responses from the DNS Server, but not being able to connect using IP when Ping reports a clean connection has me baffled.
Windows XP Home v. 5.1 (SP2) - to my knowledge the connection was fine after the user installed SP2; other computers on LAN are XP Pro SP1, so that's one difference...
Gateway is SMC (NAT router); no change to router configuration since laptop connection worked fine.
Thanks for your time!
