I'm looking for an application that will allow me to have a windows server reboot if it cannot ping a specific ip or URL after a predesignated amount of time AND on a schedule of my choosing. What's available?

It sounds simple enough for a script (VBscript/Powershell), or even a program written in a free version of Visual Express would do.

Here's a very simple VBscript to start with:

On Error Resume Next

Dim strTarget, strPingResults
strTarget = "10.0.1.11" 'IP address or hostname

Set WshShell = WScript.CreateObject("WScript.Shell")
Set WshExec = WshShell.Exec("ping -n 3 -w 2000 " & strTarget) 'send 3 echo requests, waiting 2secs each
strPingResults = LCase(WshExec.StdOut.ReadAll)
If InStr(strPingResults, "reply from") Then
'	WScript.Echo strTarget & " responded to ping."  

Else
'	WScript.Echo strTarget & " did not respond to ping."
	Set WshExec = WshShell.Exec("shutdown /r /t 1") 'reboot within 1 second
End If

Open in new window


More logic and programming can be added if it's too simple. You can just schedule this as many times as you want.

Thanks for the reply. What I was originally looking for was an application that would automate this for me. I was not able to, so I went with two scripts. One is a batch file and the other a vbs file that calls it so I could run silently. Here is what I did.

The VBS script:
Set WshShell = CreateObject("WScript.Shell" ) 
WshShell.Run chr(34) & "c:\batchfiles\autoreboot.bat" & Chr(34), 0 
Set WshShell = Nothing 

Open in new window


The Batch File it calls:
-------------------
REM: Reboot on Network Failure

@echo off

set /a counter=0

:start

ping google.com > %temp%\pinglog.txt

find "Reply from" < %TEMP%\pinglog.txt > nul

if errorlevel 1 (set /a counter=%counter%+1)

if not errorlevel 1 (set /a counter=0)

set /a timeout = 100 - %counter%

if %counter% GEQ 4 (echo System reboot imminent, please press ctrl-c in the next %timeout% seconds to abort)

if %counter% GEQ 100 (shutdown -r)

goto :start

-----------------

Open in new window

Yes, that's basically the same. What feature is now lacking that you need a program to do it? Scheduled tasks controls the schedule, I don't see what other features you need?

I was looking for an application but settled for two scripts to do the same job.
