I have 2 PCs on my home network currently. Is there any
way to turn on Pro PC by using the XP PC (and vice versa)?

Also, I'm trying to use the net send command to send
messages and it's not working. Both PCs are correctly
networked.

error message: "An error occurred while sending message
to (name of computer). The message alias could not be
found on the network. More help is available by typing
NET HELPMSG 2273."
