Adding a Client Machine IP Address to the Remote Management Computers computer set ( Requirements for Step # 13 above )

TMG comes with predefined set of policies, called the System Policy. One of these policies is for allowing remote management of TMG server. What you will need to do is to add the required computer, address range or subnet to the Remote Management Computers computer set so that you can be able to connect remotely to the TMG Server. I have previously written a complete step by step article on this topic, you can find the article here : Administrating ISA Server 2006 Remotely Using MMC and Remote Desktop Connection

Below is a quick step by step for this task:

• From the left side pane, click on the Firewall Policy node
  
  
  

• On the right side pane, under the Tasks tab, click on Edit System Policy
