One of my customers came across a rather strange problem with ISA Server 2006 Standard Edition. A report configured to generate automatically sometimes shows status as “Generating” on the Reports tab of the ISA Management Console.
The ISA Server Job Scheduler service makes sure that scheduled ISA jobs (such as generating reports) run on time.
I suggested that the ISA Server Job Scheduler service be restarted, and the problem went away. I guess the ISA reporting needs a little oiling from Microsoft (perhaps in SP1).
