SYMPTOMS
When you view the Sessions tab after you click Monitoring in the Microsoft Internet Security and Acceleration (ISA) Server 2004, you may experience all the following symptoms:
 * A connection to the ISA Server computer from an external client appears.
 * A connection from an external client to a server that you published by using a Web publishing rule appears.
 * A connection from an external client to a server that you published by using a server publishing rule does not appear.



CAUSE
This issue occurs because of the functionality of sessions in ISA Server 2004. A connection between any two host computers through the firewall can belong to only one session. In a scenario where the ISA Server 2004 computer is the endpoint for a connection, such as a Web publishing rule, the session between the client computer and ISA Server appears. In a scenario where you publish a server by using a server publishing rule, that published server has a session with the firewall. Connections to this published server belong to the server's session. Because a connection between any two hosts can only belong to only one session, no client session appears.



MORE INFORMATION
For additional information about sessions in ISA Server, see the &quot;Sessions&quot; topic in ISA Server 2004 Help.
