Answer 1

This error may occur when access to the Windows Update site is blocked because one or more of the following conditions is true:

# A firewall on your computer or local network is interfering with your connection to the Windows Update site.

# The Windows Update Web site is mapped to a specific IP address in the HOSTS file on your computer. Microsoft does not recommend the use of entries for the Windows Update Web site in the HOSTS file because the IP addresses for the site can change. NB: This issue has been reported with Internet enhancement programs (such as TweakMASTER DNS) that can add entries to your HOSTS file without your knowledge.

# The MTU setting on your router is too high/low.

# Proxy server settings are interfering with your connection to the Windows Update site.

# Norton Internet Security 2003 may be blocking access.

To try and resolve the error 0x80072EFD, use the following tips... After each tip test to determine whether the issue is resolved.


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.

Resolution Suggestion Two:

# Reconfigure or update your firewall program.
Reconfigure or update your firewall program so that Windows Update is not blocked, and then try to update your computer again by using Windows Update. For information about how to reconfigure or update your firewall program, see the documentation that was included with the program, view the Help files for your program, or contact the manufacturer's technical support department.
