Hi here is a script that Richard H suggested that I use for a similiar problem. It enables yuo to be notifies when the client comes back on-line...hope its of use :

Here is a script that will do it for you:

code:
--------------------------------------------------------------------------------

Break ON$sIPAddress="a.b.c.d"While "true" Shell '%COMSPEC% /C ping -n 1 ' + $sIPAddress + ' | find "TTL=" >/dev/null' If @ERROR=0 $Null=MessageBox("IP Address " + $sIPAddress + " is responding","It's Alive!") Exit 0 EndIf
Sleep(60)
Loop

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

Set $sIPAddress to the address you want to monitor.

This will check every 60 seconds, and popup a window when the IP address responds then exit.

Change the MessageBox() to "Beep" or "Play" to have a sound instead.
