如何在Windows 7 Home Premium 64bit上解决Windows Update错误8024402F？

我在家中的两台计算机上都遇到Windows Updates的相同问题，它们都运行Windows 7 Home Premium 64位。两台计算机中的一台是全新安装的，另一台曾经运行过Windows Update，但现在也无法运行。

当我使用控制面板手动检查更新时，出现错误代码8024402F：

我单击了“获得此错误的帮助”的链接，该链接在Windows帮助和支持中提供了几篇文章，这些文章都不是针对此特定错误代码的。通过帮助和一般谷歌搜索，我尝试了：

• 检查互联网连接。大多数帮助表明此错误是由一般的Internet连接问题引起的。但是，如果您正在阅读本文，那么我的连接肯定可以正常工作。
• 暂时禁用防病毒程序并尝试运行Windows Update。这没有帮助（我免费运行AVG）
• 运行控制面板->故障排除->安全系统->修复Windows Update问题。这表示已检测到并解决了问题，但无济于事。

• 使用IE更新（就像我以前在XP中一样）。转到http://windowsupdate.microsoft.com/将我重定向到http://test.update.microsoft.com/windowsupdate/v6/vistadefault.aspx，IE显示“连接问题”（即站点无法访问）

I've had the same problem for 24 hours now, so surely the Windows Update servers haven't been down this whole time? A quick check on twitter shows no worldwide outcry about Windows Update being unavailable, so is it just me? I'm based in the UK, but I notice that the http://test.update.microsoft.com/windowsupdate/v6/vistadefault.aspx URL is also unavailable using ''wget'' from my webserver in Chicago.

Edit 2: Suggestions from Microsoft Support:

Configure the connection to obtain an IP address automatically

1. Click "Start", input "NCPA.CPL" (without quotation marks) to Start Search bar and press "Enter".
2. Right-click the network connection and click "Properties". If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Click to highlight "Internet Protocol Version 6 (TCP/IPv6)" and click "Properties".
4. Check "Obtain an IP address automatically" and "Obtain DNS server address automatically".
5. Click "OK".
6. Click to highlight "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties".
7. Check "Obtain an IP address automatically" and "Obtain DNS server address automatically".
8. Click "OK".
9. Reboot the computer.

I tried that and IPv4 and v6 were both already set to these settings, rebooted anyway, error still there. I then sent my System Information and WindowsUpdate.log file to Microsoft, sorry but I'm not posting their contents here.

Will keep you posted on progress.
