IE7 lost internet connectivity - pls Help to restore

I have a new laptop and I accidentally turned off interne
connectivity...
I need help to turn it back on, please.

Here is what happened:
New pc, Vista Home Premium, running IE7 7.0.6000-00141

(I am using another pc to get online.)

In IE7, it was repeatedly nagging me about "IE wants to be
used as a server..." Allow or Deny... I got tired of this an
clicked
"do not ask me this again" + DENY.

Web access is blocked now.
The IE7 URL defaults to res://ieframe.dll/dnserror.htm# and it "cannot
display the webpage". Windows Network Diagnostics "did not find
any problems with this computer's network connection"

I can still ping the router and yahoo.com from a cmd prompt.
Other programs still have full access to internet.

It has affected ALL profiles...

I am asking for help to tell me how to find the setting and to und
this
change!

Many thanks in advance
