...you could be researching a Lights-out-Management solution for your

server (Dell DRAC, Sun LOM).  Best all-around solution is a  PC-Weasel

(realweasel.com) connected to the system next to it (Or a RAS

concentrator)
If the system is completing 3-way TCP handshake, then you're dead in the

water.  Consider making the system highly available.
