I cant understand this question.but i wrote what i know

We can check from the server by using PING command.

We should use give the client name or IP address followed 
by the ping commands.

For example ping 128.0.0.156 -n 4

where -n and the 4 is no echo requests to send times.

if the client is connect with the server the reply is coming
with some informations.
