ISA 2000 Service

The ISA 2000 service monitors the availability of the Microsoft Internet Security and Acceleration (ISA) server, which serves as an enterprise firewall and a cache server. The ISA firewall scans circuit, application, and packet data and the ISA cache server manages Web page requests and provides faster access to frequently used sites by saving them. 

During the monitoring process, the ISA 2000 service uses the Windows probe to measure the ISA server's key metrics. The results are then displayed on the dashboard for the service.
