I learned this a long time ago. It helps when building multiple servers, you’ve got a deadline and you need to reboot one or more. Simply, fire up a command prompt and add the –t switch to the end of the ping command.
Ping ###.##.##.## –t
or
Ping <<ServerName>> –t
The –t will continually ping the server until you stop it (with Ctrl-C)….So after the server shuts down, you’ll get a Request Timed Out – every second until it’s back up. Once you start seeing a response, it’s on the network – it may take another minute or two to be able to RPD to it.
