<div class="symptoms_section">

SYMPTOMS
When you try to connect to the Windows Update Web site (http://windowsupdate.microsoft.com), you may be unexpectedly redirected to a Web page that displays a message that is similar to the following:

Thank you for your interest in Windows Update

Windows Update is the online extension of Windows that helps you get the most out of your computer ...

<div class="cause_section">

CAUSE
This behavior may occur for any of the following reasons:
 * You are not running a release-to-manufacturing (RTM) (non-beta) version of Windows 98, Windows 98 Second Edition, Windows Millennium Edition, Windows NT 4.0, Windows 2000, Windows XP, or Windows Server 2003, or you are running Windows 2000 Datacenter Server.
 * You are not running an RTM version of Microsoft Internet Explorer 5 or later. For example, you are running a beta version of Internet Explorer, or you are not running Internet Explorer.
 * Windows Update incorrectly detects that you are not running a released version of Internet Explorer 5 or later on a supported Windows operating system. This may occur if you access the Internet through a firewall or proxy that does not allow the Windows Update Web site to receive the correct HTTP user-agent request header (&quot;HTTP_USER_AGENT&quot;) for Internet Explorer. Windows Update uses the operating system information that the navigator.userAgent property returns to determine if you are running a supported operating system. Some firewalls or proxy servers may send user-agent information that is incorrect or difficult to interpret.

<div class="resolution_section">

RESOLUTION
To use Windows Update, you must be running an RTM version of Internet Explorer 5 or later on a Windows 98, Windows 98 Second Edition, Windows Millennium Edition, Windows NT 4.0, Windows 2000 (except Datacenter Server), Windows XP, or Windows Server 2003-based computer. To resolve this behavior, use the appropriate method:

Method 1: Upgrade Windows or Internet Explorer
If you are not running an RTM version of Windows 98, Windows 98 Second Edition, Windows Millennium Edition, Windows NT 4.0, Windows 2000 (except Datacenter Server), Windows XP, or Windows Server 2003, or you are running a beta version of Internet Explorer or a version of Internet Explorer earlier than version 5, then upgrade to the latest released version of Windows and Internet Explorer. For more information about how to determine which version of Internet Explorer you are running and how to upgrade it, click the following article number to view the article in the Microsoft Knowledge Base:

164539 How to Determine Which Version of Internet Explorer Is Installed

Note Windows Update does not currently support updates for Windows 2000 Datacenter Server. Contact your service provider to receive updates to Windows 2000 Datacenter Server.

Method 2: Use Internet Explorer 5 or later or the Microsoft Download Center
If you are using a non-Microsoft browser, you can instead either use Internet Explorer 5 or later to access the Windows Update site or download updates from the Microsoft Download Center by using your non-Microsoft browser:

http://www.microsoft.com/downloads/search.aspx

Method 3: Configure your firewall or proxy to allow Windows Update to receive the Internet Explorer user-agent request header
Configure your firewall or proxy to allow Windows Update to receive the HTTP user-agent request header that Internet Explorer sends. Contact your network or system administrator or see the documentation included with your proxy or firewall for information about how to do this. For information about how to contact your firewall or proxy vendor, click the appropriate article number in the following list to view the article in the Microsoft Knowledge Base:

Method 4: Modify the registry
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
