You have a choice to make.

To get a "real time" status, you must have a client on the target machines that checks-in with a central database to give it's status. Obviously, a machine that's off cannot give a status so the client application has to check-in when the user hits Windows Shutdown. It would also check-in with a status of Up when the app starts and possibly even check-in with that status every so often. This gives you a current status and you don't have to wait for a report to be generated.

Pinging every machine on the network will not give you a "real time" status, but the known status the last time the machine was pinged. If you have a small number of machines, this can give you a status of every machine fairly quickly. This status will fall farther and farther behind the larger the number of machines you have to get a status on. This gives the status of all machines but you have to wait for that status to be generated when you want the report.

To prevent this delay, to a point, you would have to have a service running on a server somewhere that just pings the machines all the time and updates the database. This will give a report of the status of the machines the last time it was pinged but you wont have to wait for the report to be generated. Again, even this will fall behind as the number of machines increases.

The problem with pinging machines is that the firewalls on them can be configured to block ICMP packets causing the pings to fail and look like the machine is off.
