I do a lot of work with different firewalls including Microsoft ISA Server. As with any firewall, there is always something to troubleshoot. User can't access particular website, another user didn't receive his e-mail etc. These are all reasons why we need a good and fast way to filter and analyze firewall logs.
In ISA Server 2004 and 2006 there are few new features that come with updates and allow firewall administrators to save existing queries in XML file and reuse them at a later time.

For me this is really a time saver. Now I don't have to waste time and write same filters over and over again (e.g. excluding specific traffic and including other). I can simply carry most common queries on my USB drive and import them whenever I need them.
On ISA Server 2004, you get these new features when you install Service Pack 3 (SP3) for ISA Server.
On ISA Server 2006, you can get these features by installingISA Server 2006 Supportability Update that you can download manually or you can use Microsoft Update Service.
