An established connection does not appear on the Sessions tab in ISA Server 2004

Article ID: 838129

Article Last Modified on 7/16/2004



APPLIES TO

  • Microsoft Internet Security and Acceleration Server 2004 Standard Edition




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 "Sessions" topic in ISA Server 2004 Help.
