Internet Explorer Does Not Connect Using 128-Bit SGC Encryption

ID: Q244302

The information in this article applies to:

Microsoft Internet Explorer version 5 for Windows NT 4.0
Microsoft Internet Explorer version 5 for Windows 98
Microsoft Internet Explorer version 5 for Windows 95
Microsoft Windows 98 Second Edition

SYMPTOMS

When you attempt to connect to a Web server with Server Gated Cryptography (SGC) encryption, you may not be able to connect if you attempt to connect by using the site's IP address instead of the site's fully qualified domain name.

CAUSE

This behavior occurs because of an error in the way Internet Explorer handles the SGC negotiation. Instead of not allowing the 128-bit connection and making a 40-bit connection, the connection is being denied.

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next release of Internet Explorer (version 5.01) that contains this fix.
