Programming :: Write DOS Script To Monitor The PC's Network Status?

There are a few PCs on the network that lose network connection every so often -- sometimes these old beasts have a power failure and owing to a bug in the BIOS the NIC doesn't necessarily initialize properly, which requires a reboot to correct it. Got me thinking of a band-aid -- have the PC ping a specific IP address, and if it cannot ping then it forces itself to reboot.

IF I were to write it in BASH I'd do it like this:

#!/bin/bash
HOST=<some meaningful hostname or IP address>
for ipaddy in $HOST
do
count=$(ping -c 1 $HOST | grep 'received' | awk '{print $4}')
if [ "$count" = "0" ]; then
sh usr/bin/reboot
fi
done

In English: send 1 ping to the IP address. Grep through the results to see how many of 1 ping was returned. IF it returns 0 pings then reboot. I'm sure the reboot command would have to be groomed a bit for sudoers but that's beside the point here.

So, HOW do we write something like this for DOS? Stop giggling (lol). No really, I have Windows 2000 & XP machines that need some sort of script or method of knowing (at intervals) of when they're not talking to the Host system, and need to reboot to fix it. I was thinking to write a simple test script, drop it on each of these machines and use the Windows task scheduler to run it every 30 minutes.
