I have two workstations within a network. I know really little about networking, so I'm not sure what kind of network it is. Both machines have WinXP and they can see one another's IP number.
Let's call them A and B (B acts as a files server for several machines).
I have set both to power on at 9 pm from the system BIOS. After the boot process, A shows the log-on screen. B, however, does not show this log-on screen (Windows and all scheduled tasks start working normally).
At 9:15 PM B does an information backup to A (yes, although A hasn't logged, it is still visible to B and the backup job is done alright).
Some hours later, when the backup job is supposed to have finished, I'd like both workstations to shut down.
For machine B I've written a small AutoIt script that will shut it down 2 hours later if it's a weekday; if it's Saturday or Sunday, it will shut down the computer before the backup is run (since there's no HD activity on Saturdays and Sundays, doing a backup would just create exact copies of the Friday backup).
Now, my problem is: how do I shut down computer A? Since the boot process stops at the logon screen, no programmed tasks are ever run, nor AutoIt scripts can be launched at startup.
Is it possible to remotely shut down A? Maybe some kind of ping from B? Any clues?
