Resolution Suggestion One:
# Test your Internet connection to Windows Update.
A simple solution but one that works in many circumstances!
Test to determine if your Internet connection is preventing you from
reaching the Windows Update Web site. To do this, visit the following
Microsoft Windows Update Web site to determine if you can download the
Iuident.cab file:
http://windowsupdate.microsoft.com/v4/iuident.cab
If a file download dialog box appears, the problem is not with your
Internet connection. Click Cancel. If you cannot connect to this link,
and you receive a "Page Cannot Be Displayed" error message, your
Internet connection is preventing you from reaching the Windows Update
site.
I TRY THIS OPTION AND I HAVE NO PROBLEM
