SSL: Connections May Fail Using Online Requested Certificates

• Microsoft Internet Information Server version 4.0
• Microsoft Certificate Server version 1.0

SYMPTOMS

When you try to connect using Secure Sockets Layer (SSL) to an Internet Information Server version 4.0 (IIS) that has a server certificate from an online Microsoft Certificate Server, you may receive the following error message:

Internet Explorer cannot open the Internet site <address>
A connection with the server could not be established.

CAUSE

When you perform an online request, the certificate returned by Certificate Server is not bound with an IP address or port number. As a result, IIS does not use this certificate for incoming SSL connections.

WORKAROUND

When you get the certificate back from the online request, a dialog box appears in Key Manager. Click Add, and then click OK. The certificate is now bound to all unassigned IP addresses and port numbers.

MORE INFORMATION

NOTE: The above steps are not required if the certificate is requested from a well-known certificate authority, such as VeriSign, or when you are requesting a certificate from Certificate Server through the file-based mechanism (that is, not an online request).

IIS 4.0 ships with a tool named Key Manager, Keyring.exe, to request and process server certificates. One of the options is to request a certificate from an online Microsoft Certificate Server. Online indicates that Certificate Server is running on the same computer as IIS, and the request is made without using a text-based approach.
