While the Windows Update Web site is loading, you receive Initialization error 0x80072F78
Problem Description:
Windows Update has encountered an error and cannot display the requested page.
Resolutions:
This error is proxy/firewall related, so double-check your firewall/proxy settings. Try disabling your firewall and see if the error persists. CheckPoint Firewall is one product that is a known culprit of this error. Make sure that TCP/IP ports 80 and 443 are open in both directions. Make sure your firewalls are not blocking scripting functions on web site. This error is the result of your PC's inability to connect to a component of the Windows Update site. Disable all 3rd party applications (like Anti-Virus software) before accessing the site. Here are a few ways to try to resolve this issue:
Suggestion 1
===========
Check your HOSTS file (it may also be called HOSTS.SAM) and make sure you don't have any static IP entries for the Windows Update web site listed in the file. If you are running Win98/ME, the HOSTS file will be in this folder:
C:\Windows
If you are running WinNT/2K/XP, it will be in this folder:
C:\WINDOWS\system32\drivers\etc
You can use Notepad to open the HOSTS file. You may need to "tell" Windows to use Notepad to open the file.
Applications like web accelerators, TweakMasterDNS, etc. can add static IP entries for the Windows Update site into your HOSTS file and when this happens you will get the 0x80072F76 error message.
