As the title. If the network is detected to be unavailable, the computer will automatically restart after 5 minutes. Thank you

``` :start ::Change this IP to the address you use to detect the network, such as the gateway ping 10.10.37.254 -n 1 > nul ::-t The number behind is how many seconds to wait before restarting if %errorlevel% neq 0 shutdown -r -t 300 goto :start ```

Thanks, I just tried it, it's quite good. Add another question, is there a command that can repair the network connection? My idea is like this: The server itself has been running this P. When it is found that the network is not working, it will automatically repair the network. After the repair is completed, it will automatically restart the computer. I mainly want the server to repair itself. Thanks

There are many reasons for network disconnection... If this could be done automatically, a large number of network administrators would be out of work

After thinking about it, the code provided earlier is still not good enough. After losing network connection, it will keep executing shutdown. We should set up to jump out of the loop. :start ping 10.10.37.254 -n 1 > nul if %errorlevel% neq 0 ( shutdown -r -t 300 goto :end ) goto :start :end

Thanks! You this one restarts as soon as it doesn't work. If the network flashes and breaks when it's just PINGing, that's not good, right? I think it should restart the computer when PING has been uninterrupted for 2 minutes, can that work?

This method is obviously not a way to ensure server stability and network stability.

But the company doesn't want to buy equipment, so we have to make a simple one by ourselves.

This is what I thought. If the above assumption is solved, then I will find a short message sending device. If the network is still not working after restarting the computer, it will automatically send a short message "XX server network interruption". Is it feasible?

Is it feasible? It is to use the interface of Feixin to send free short messages. Feixin message sending program http://www.cn-dos.net/forum/viewthread.php?tid=48736&fpage=1&highlight=

Still, the loop should be set to break out :start ping 10.10.37.254 -n 1 > nul if %errorlevel% neq 0 ( ... Sorry Tried it, but it's still an infinite loop

Hello! Can this be done? First ping a machine, if it's not reachable, then continue pinging for 1 minute. If it's still not reachable, then restart the computer, and it's not a dead loop, thank you!
