The centerpiece to ISA Server 2004 is the Management Console. The ISA Management Console contains the majority of the features and tools that are necessary for configuring ISA's various functions. Firewall rules, network rules, caching configuration, VPN functionality, and many more functions are contained within the console itself, and an understanding of ISA is incomplete without a good familiarity with the Console.
Defining ISA Server Console Terminology and Architecture
The ISA Server 2004 Console, shown in Figure 3.1, is a vast improvement over the ISA 2000 Console, which was not very logically structured and made information and tools difficult to locate. The 2004 Console, on the other hand, logically groups common tasks together and structures the tools and information in a way that is intuitive and convenient.
Figure 3.1. Viewing the ISA Server 2004 Management Console.
The ISA Console can be launched by clicking Start, All Programs, Microsoft ISA Server, ISA Server Management. Because of the way the Console is structured, it is best viewed at a screen resolution of 1024x768 or greater.
Exploring ISA Console Panes
Each area within the ISA Server Console has a specific name by which it is referenced. The names of these areasor panes, as they are calledmake it easier to identify where specific information is, and provide a common language that can be used when troubleshooting ISA issues. This book refers to the particular panes by name throughout the chapters, so it is important to understand the terminology in advance. The following is a list of the panes included in the ISA Console and their respective functions:
When not in use, the Task pane can be hidden from view by clicking on the Open/Close Task Pane arrow, which appears as long oval with a > arrow in the middle of it. To open the Task pane back up, simply click on the Open/Close Task Pane arrow again. If you close the Task pane when it is not needed, more space is available for viewing rules or monitoring ISA configuration.
Examining ISA Console Nodes
The Scope pane contains a list of nodes, or logical configuration units that group together tasks and views related to a specific portion of ISA functionality. Clicking on each node in the console tree displays the information that is particular to that node. For example, Cache-related information is stored in the Cache node, VPN information in the Virtual Private Networks node, and so on.
Switching between nodes involves just clicking on each individual node in the Scope pane. Each time a new node is selected, the information displayed in the Central Details pane and the Task pane changes to display information specific to that particular node.
The nodes available in ISA Server 2004 Standard Edition are the following:
Additional information about the contents of each of these nodes is provided in the next sections of this chapter.
ISA Server 2004 Enterprise Edition contains several additional nodes, not listed in this list. For more information on the Enterprise-specific nodes, refer to Chapter 6, "Deploying ISA Server Arrays with ISA Server 2004 Enterprise Edition."
