My servers are leased so if anything goes wrong and a reboot is needed I have to wait for my provider to preform it.

In this post we will create a vb Script that pings an IP address and reboots if it can’t see it. We will simply run it on a timer using the command scheduler.

Here is the script:

Option Explicit

dim strHost

‘The ip address you want to monitor
strHost=”111.222.333.444″

if Ping(strHost) = True then

‘You can do stuff here if you want.

Else

‘The next three lines reboot

dim objShell
Set objShell = CreateObject(“WScript.Shell”)
objShell.Run “shutdown /r /t 000″

end if

‘the following is a subroutine called above

Function Ping(strHost)

dim objPing, objRetStatus

set objPing = GetObject(“winmgmts:{impersonationLevel=impersonate}”).ExecQuery(“select * from Win32_PingStatus where address = ‘” & strHost & “‘”)

for each objRetStatus in objPing
if IsNull(objRetStatus.StatusCode) or objRetStatus.StatusCode<>0 then

Ping = False

else
Ping = True
end if
next
End Function

Just save this to a vbs file and add

cscript c:\ping.vbs

to “Scheduled tasks” every 15 minutes.

‘Till next time…
