Lately we had received some calls where ISA Server was not using the latest updates, which is fine although is not recommended. However when the subject is Service Pack then it might be a supportability blocker if ISA Server is not running within the supported Service Pack level. ISABPA does a great job in warning an ISA administrator that his ISA Server 2004 is not running with SP3 as shown below:

But today the issue is not only having the system with the latest update, is really a supportability matter. ISA Server 2004 SP2 is not supported since January 13th 2009 as shown in the table below:

So if you are in an unsupported scenario (or about to get into this stage) make sure to plan your update as soon as possible to avoid supportability concerns when opening an incident with Microsoft CSS.
