Figure 9 — Schema initialization has been completed. Now that we have done all of our preparatory work, we can now move on to the actual process of installing ISA Server on our machine as follows:.
Figure 10 — Choosing the type of installation to perform. Figure 11 — Looks like someone forgot to install SP1 on the Server! Figure 13 — Installing as a stand-alone server. Figure 14 — Selecting the mode of the server. On the next window, you must configure the cache size. This option, like most others can be changed after installation is complete. The default setting is for a MB sized cache, and for now we will leave it be.
Click OK to continue. The next step, one of great importance if you want this whole thing to work properly, is to construct the LAT table. The easiest way to do this is to click the Construct Table… button and select the range for the internal network adapter as shown in Figure The results of this are shown in Figure Click OK to continue past this step. Figure 16 — Selecting local addresses.

To test the ISA Server, you can create an "all open" rule to allow access to all Internet sites and protocols; but in a production environment, you'll want to limit access.
You can delegate administration of the ISA Server and assign different administrative roles to users or groups based on what each firewall administrator needs to be able to do. This allows for better security. There are three defined administrative levels:.
You can define administrative roles by invoking the Administration Delegation Wizard. On the Tasks tab in the right pane, click Define Administrative Roles. This starts the wizard, which will walk you through the process of delegating control to users or groups. I recommend that you assign roles to groups rather than individual users.

Internet Security and Acceleration ISA Server Architecture ISA Server integrates robust firewall and caching capabilities'providing performance and security enhancements to networks that connect to the Internet. Firewall and Security ISA Server serves as a firewall, providing secure Internet communication by preventing unauthorized network access.
The firewall functionality is transparent to the other parties in the communication path. The intranet user is unaware that the firewall is interceding, unless the user attempts to access a service or a site that has been not been approved by the administrator. Users interpret accessed Internet Web server requests from ISA Server as if they originated from the client applications.
It is also extensible for the creation of additional application filters. Distributing the cache load allows scaling beyond what a single server can provide, balancing the load, and providing fault tolerance if a cache server is unavailable.
Distributed caching can be implemented with arrays, chains, or a combination of both. Administration Using policy-based access control with ISA Server provides you with flexible policy management based on users and groups, client protocols, schedules, sites, and content groups and protocols.
Leveraging Microsoft Active Directory service and enterprise-level policies, administrators can create and apply policies once and distribute them globally to many servers. Detailed logging, alerting, monitoring, and reporting help administrators understand the status, usage, and performance of the server.
