SYMPTOMS
You use Microsoft Internet Explorer 6 on a computer that is running Microsoft Windows Server 2003 Service Pack 1 (SP1) or on a computer that is running Windows Server 2003 Service Pack 2 (SP2). You use this computer to connect to a secured Web site that requires a client certificate. However, you do not receive the certificate selection prompt. Additionally, you receive the following error message:

The page cannot be displayed

<div class="cause_section">

CAUSE
This problem occurs because of a code change that was made in the Schannel.dll file. This file is included in Windows Server 2003 SP1 and in Windows Server 2003 SP2. This change lets the Secure Sockets Layer (SSL) client reconnect to the Web server by using the credentials that are stored in the cache for the current session. The client may have to reconnect if the client receives a request to start a new session. The client may also have to reconnect if the client requests a new session. In this a scenario, Web servers that do not support the SSL client behavior expect a new session to be generated. These Web servers do not expect the client to reconnect by using the credentials that are stored in the cache for the current session. Therefore, you receive the error message when you try to connect to a secured Web site.

Technical support for x64-based versions of Microsoft Windows
If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
