I want to continuously ping a server and see a message box when ever it responds i.e. server is currently down. I want to do it through batch file.

I can show a message box as said here Show a popup/message box from a Windows batch file

and can ping continuously by

ping <servername> -t

But how do I check if it responded or not?

The question was to see if ping responded which this script does.

However this will not work if you get the Host Unreachable message as this returns ERRORLEVEL 0 and passes the check for Received = 1 used in this script, returning Link is UP from the script. Host Unreachable occurs when ping was delivered to target notwork but remote host cannot be found.

If I recall the correct way to check if ping was successful is to look for the string 'TTL' using Find.

@echo off
cls
set ip=%1
ping -n 1 %ip% | find "TTL"
if not errorlevel 1 set error=win
if errorlevel 1 set error=fail
cls
echo Result: %error%

This wont work with IPv6 networks because ping will not list TTL when receiving reply from IPv6 address.
