Bat script for reconnect VPN connection in Windows

vpn_reconnect.bat

@echo off
:loop
    echo testing IP address
    ping 123.456.78.90 >nul || (
       echo ping failure - disconnecting
       rasdial name_of_your_vpn_connect /disconnect
          timeout /t 10 /nobreak
       echo reconnecting
          rasdial name_of_your_vpn_connect
          timeout /t 10 /nobreak
   )
timeout /t 30 /nobreak
goto :loop

In the year 2017, system administrators still have to reconnect the VPN connection using loops in the bat script ;(
No, I know about the task scheduler, and about carrying out tasks on events - but they do not work stably.
If you know a way how to make this kind of tasks through the scheduler more stable, please write in the comments.

Hello from 2020 =)
A little improved version:

@echo off

set VPN=Your_VPN_Name
set USERNAME=Your_VPN_User_Name
set PASSWORD=Your_VPN_Password

:loop
    cls
    echo Checking connection availability...
    ipconfig|find /i "%VPN%"
    if %errorlevel%==1 goto:reconnect
    timeout /t 30 /nobreak
    goto :loop

:reconnect
    echo Disconnecting...
    rasdial "%VPN%" /disconnect
    timeout /t 10 /nobreak
    echo Connecting...
    rasdial "%VPN%" "%USERNAME%" "%PASSWORD%"
    timeout /t 10 /nobreak
    goto :loop

This version checking existing ipconfig adapter connection to detect current VPN connection

@echo off
