Error 0x80072F76

[Eep²]

Windows 2000 SP3

Well, I get the same error number but I have no web accelerators and I've tried everything on http://v4.windowsupdate.microsoft.com/troubleshoot/ (see below) to resolve this error but nothing works. I can download http://windowsupdate.microsoft.com/v4/iuident.cab fine.

The error in "Windows Update.log" is:

2004-03-23 10:38:09 18:38:09 Success IUCTL Starting
2004-03-23 10:38:09 18:38:09 Error IUCTL Library download error. Will retry. (Error 0x80072F76)

2004-03-23 10:38:10 18:38:10 Error IUCTL Failed to download iuident.cab from http://www.windowsupdate.com/v4/ to C:\Program Files\WindowsUpdate\V4\temp (Error 0x80072F76)

While the Windows Update Web site is loading, you receive Initialization Error 0x80072F76

Problem Description:
User receives a 0x80072F76 error when visiting the Windows Update Site. The Windows Update.log file will have error entries similar to the following:
2002-11-25 23:25:11 04:25:11 Error IUCTL Failed to download iuident.cab from http://windowsupdate.microsoft.com/v4/ to C:\Program Files\WindowsUpdate\V4\temp (Error 0x80072F76)

Resolutions:
This is a blocking issue. The client computer is unable to connect to a component of the Windows Update site. Most likely this is due to misconfigured proxy/firewall settings, incorrect DNS entries or some application running on the client computer that interacts with Web connections and is blocking the connection. 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.

Suggestion 2
===========

Check your firewall/proxy settings and also try disabling your firewall. 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 (including anti-virus) before accessing the site.

Suggestion 3
===========

You may be able to resolve this issue by adding the following Web sites to the trusted sites list in Internet Options:

http://Windowsupdate.microsoft.com
http://V4.Windowsupdate.microsoft.com
https://v4.Windowsupdate.microsoft.com (Note: The https is correct)
http://Download.Windowsupdate.com

To add these web sites to the list, follow these steps:

1. Open Internet Explorer.
2. Click "Tools," and then click "Internet Options."
3. Click "Security."
4. Click the Trusted Sites icon.
5. Click "Sites."
6. Clear the check box "Require server verification (https:)for all sites in this zone."
7. Add all four sites listed above.

Suggestion 4
===========

This issue may be resolved by adding the Windows Update sites to the exceptions list in the Internet Options Proxy Settings.
To access the Exceptions settings:

1. Open Internet Explorer
2. Click "Tools" and then click "Internet Options."
3. Click "Connections" and then click "LAN Settings."
4. Click "Advanced" and add windowsupdate.microsoft.com; v4.windowsupdate.microsoft.com, and download.windowsupdate.com to the exceptions list.If you run other proxy/firewall software, then add the sites to the exception list for those applications as well.

Suggestion 5
===========

As a test, try this link:

http://windowsupdate.microsoft.com/v4/iuident.cab

When you click this link, you should see a popup message asking if you want to Open the file, or Save it to your computer. If you are unable to connect to this link and see a Page Cannot Be Displayed-type error, then this confirms that some aspect of your Internet connection is preventing you from reaching the Windows Update site.

Suggestion 6
===========

This error may also occur with Mailgate from http://www.mailgate.com/ previous to version 3.5.171 beta where the issue seems to have been corrected.
The excerpt below is from the release notes for the MailGate 3.5.171 Beta:

1.1 SDR0137 - Added support for the HTTP HEAD command in the Web proxy. This command is used by the Microsoft Windows XP update service.

It looks like a program is intercepting the process. What firewall are you
running? You may need to configure your firewall to run Windows Update.
Try a clean boot.

My firewall is fine; the error still happens even if I completely bypass the firewall anyway. Clean boots make no difference either.
