Consider the following scenario:

• On a Windows Vista-based computer, you create a connection security rule that uses a computer certificate.
• In this security rule, you enable the Accept health certificates only option.

In this scenario, the local-to-local connection is broken on the Windows Vista-based computer.

For example, assume that you start Internet Information Services (IIS) on the Windows Vista-based computer. When you try to connect to the local address by entering either “http://localhost” or the local IP address in Internet Explorer, you discover that the connection is broken.

Note: This problem does not occur if the Accept health certificates only option is not enabled or if Kerberos authentication is used.
