You really need to go through and make sure that all of the networking equipment is connected to surge suppression equipment so this doesn't happen again. The LAN should all be closed off from future surges at that point. It's most likely that all the ruined pc's were connected to the same unprotected switch. Might also just be a bad switch, and not really lightning.
