Article ID: 831167 - View products that this article applies to.
You may not be able to log on to a Web site or complete an Internet transaction after you install the 832894 (MS04-004) security update. For example, when you submit your user name and password to an SSL-secured Web site by using a form on a HTTPS Web page, you may receive an HTTP 500 (Internal Server Error) Web page.
This problem may occur after you apply the 832894 security update (MS04-004) or the 821814 hotfix on a computer that runs Microsoft Windows XP, Windows 2000, Windows NT 4.0, Windows Millennium Edition, or Windows 98.

821814The 832894 security update (MS04-004) and the 821814 hotfix change how the Internet extensions for Windows (Wininet.dll) retries POST requests when a Web server resets the connection. Programs that use Windows Internet (Wininet) application programming interface (API) functions to post data (such as a user name or a password) to a Web server retry the POST request without including the POST data if the Web server closes (or resets) the initial connection request.
(http://support.microsoft.com/kb/821814/ )You receive a "page cannot be displayed" error message when you post to a site that requires authentication
Note A POST request does not include POST data if its content length is set to 0 or is empty.
Sometimes, this behavior prevents another reset and permits authentication to complete. However, you may receive an HTTP 500 (Internal server error) Web page if the Web server must have the POST data included when Wininet retries the POST request.
