Error message after you install a Windows Internet Explorer 7 update from
Windows Update or from Microsoft Update: "Webpage cannot be displayed":
http://support.microsoft.com/kb/942818

If tweaking your third-party firewall's settings don't help, try the
following:

1. Disable your anti-virus application, all Norton Add-ons (if any), any
real-time protection provided by an anti-spyware application (except for
Windows Defender; includes Spybot Tea Timer, SpySweeper Guards, AVG AS
guard.exe, etc.), disable any third-party firewall AND THEN enable the
Windows Firewall.

NB: You're "working without a net" now: Don't to ANYTHING else online (e.g.,
browsing; reading email; chatting) except #4 below until your anti-virus
application has been re-enabled!  If you're running ZA Free firewall, you
may need to uninstall it instead of disabling it.

2. Uninstall "Security Update for Windows Internet Explorer 7 (KB950579)"
via Add/Remove Programs (make sure Show Updates box is checked at top right)
and reboot.

3. Re-do #1 above.

4. Go to http://windowsupdate.microsoft.com and install any Critical Updates
offered.  If  a Root Certificates update is listed in the Optional Updates
category, install it to take full advantage of IE7's enhanced security.

5. Reboot > Make sure everything in #1 above is enabled again and, if
applicable, disable the Windows Firewall and enable (or reinstall) your
third-party firewall.

=====================================

For home users, no-charge support is available by calling 1-866-PCSAFETY in
the United States and in Canada or by contacting your local Microsoft
subsidiary.  There is no-charge for support calls that are associated with
security updates.  When you call, clearly state that your problem is related
to a Security Update and cite the update's KB number (e.g., KB123456).

LOOK! => If your problem relates to a Cumulative Security Update for IE,
call the above number and ask to be transferred to the Consumer IE7 queue
(which is 47830).

For more information about how to contact your local Microsoft subsidiary
for security update support issues, visit the International Support Web
site: http://support.microsoft.com/common/international.aspx

For enterprise customers, support for security updates is available through
your usual support contacts.

Then that means that you have something running normally which
is blocking IE's connectivity.   You could use  Task Manager's Processes
tab each time and compare what is running normally that isn't running
in safe mode; however there are better tools to use to try to identify
the problem task.

E.g. issue  tasklist  (in a cmd window)  in each case.   If you don't
have  tasklist  you could get a similar effect from

   msinfo32.exe  /category  SWEnvRunningTasks

I'm suggesting you try either of those instead of  Task Manager's  Processes tab
simply because they allow you to capture the running tasks and thus will make
a comparison of the two cases easier.   Process Explorer  if you have that could
also be used to capture such a list.

So, you have to be a bit more discriminating in your diagnosis...  ; )

Oh.  You mean something took over your  DNS  adddresses and hardcoded them?
That could be a sign of a malware infection...

In any case, while you are in a cmd window enter:

   ipconfig  /all

and see which addresses you both have under the  DNS servers line
for the active connection.

You could also use  nslookup  to see if each will do a reverse lookup
of the other.   E.g.  if from the  ipconfig  output you saw:

<ipconfig>
       DNS Servers . . . . . . . . . . . : aaa.bbb.ccc
                                                       ddd.eee.fff
</ipconfig>

then you would enter:

   nslookup  aaa.bbb.ccc  ddd.eee.fff

or

   nslookup  ddd.eee.fff  aaa.bbb.ccc

I suspect you will see that you both have dramatically different
DNS addrresses and that accounts for one not working correctly.
