Here at Swiss InterWeb we are using A1Monitor since Windows NT4 ! We use it on all our Windows servers since we can monitor plenty of different services, plus A1Monitor can trigger home made script in case of event.
One of the main advantage is the A1Monitor is very easy to install, configure and use and best of all is very economic in term of resources.
Finally its price is really attractive regarding the peace of mind it brings.
We will definitely recommend this product to any Windows administrator, beginner or advanced.
