Vista Laptop - No Internet

[seedubya]

Hi All

This one has me driven mad. Vista Home basic laptop. Was working fine at clients house until a couple of days ago. Suddenly stopped being able to connect to the net. They say no changes made or new software installed.

I now have the laptop at my place. In normal mode it can acquire an IP address (wired or wireless) but cannot surf. I can ping wherever I like from the command line but can't open any websites from firefox or IE7. Have tried resetting the winsock and TCP stack to no avail.

In Safe Mode with Networking can't connect to any network, every connection attempt times out.....

Would be grateful for any ideas.

EDIT: Cannot connect to any internal sites either e.g. Router GUI or Intranet

I assume you checked the tcp/ip to make sure they are not specifying a dns server if its a DHCP setup ?.

If you can ping but not surf then it sounds like dns or gateway or netmask issues. But if its set for DHCP all the way through then it should set all that up itself. If its set partially for DHCP and specifics for the rest then it would fail like this.

What do you see in the "status" of that network connection (ip, gateway,dns servers, etc...) ?

Are you pinging IP or domain names in the cmd prompt ?

It's set for DHCP all the way through. I can ping externally by both IP and FQDN so DNS is not the issue. I run my own SBS server internally so that's the DNS/DHCP server.

It sounds like a Proxy issue. Check your internet settings under Internet Explorer... Tools --> Internet Options --> Connections Tab --> Lan Settings and in there, nothing should be checked.

Oh, these instructions are for IE 7. IE 6 Should be similar.

Nope, first thing I checked.

Have you tried updating the NIC driver? When you try and go to a website, does it give you any kind of error message?

New development.

NIS 2007 was expired so I decided to uninstall it just to eliminate one more possible variable. It would not complete the uninstallation and now I can't even get an IP address from the DHCP server. Am about to try the Norton Removal Tool to see if there are any traces left. A friend recommended re-installing NIS and uninstalling again if that fails...........

 

[seedubya]

OK, that sorted it. Following the thread of what actually happened. NIS must have caused the original problem. Then the failed un-installation of NIS messed it up even more. Then the Norton Removal Tool (Symantec' only worthwhile piece of software) properly removed NIS which fixed the problem.

Gosh, Don't you just hate Nortons? They screw up everything.

Nice work. When I have a computer that can ping ip but can't access internet plus I've reinstalling the NIC driver, I run Norton/McAfee/Avast removal tools cause consumers love to install and uninstall multiple programs that affect internet connection. They don't know any better , but hey its good for business.
