Cannot Display Webpage but connected to Internet

I have a very similiar situation to a previous post...2 computers in 1 room connected by wireless router. Both computers are confirmed to be connected to the internet by Network Connections however one computer I can view webpages and one  two week old Vista OS Dell 9400 can not view web pages - all except  for one website...Netflix.com.   All other webpages can't be viewed -received error message "Internet Explorer cannot display the webpage".

 

Steps I have taken to troubleshoot..

1. Reset modem and router.  Shut off both computers waited 5 mins and restart modem, then router and then Dell 9400.  No change.

 

2. Followed Microsoft's  troubleshooting for "Error message in Internet Explorer 7: "Internet Explorer cannot display the webpage"

Includes - deleting browsing history,  runing network diagnostic tool, using device mgr to verify network adapter is working.

 

3.  Removing wireless router and connecting directly to modem through Cat5 cable - no change

 

Here is my ipconfig/all

 

Windows IP config

IP Routing Enabled...no

WINS proxy Enabled..no

 

Wireless LAN Adapeter Connection

DHCP enabled ...yes

Autoconfig enabled...yes

Link-local IPV6 address...fe80::3956:3ac5:ff0f:e576%10 (preferred)

Please help.  My husband keeps using my computer and is driving me nuts.
