I think that the utility ping can be useful to you. You can dissassembling its with IDA :). But if say seriosly then Dinami?? Link Library Icmp.dll consist of function IcmpSendEcho(..). This function help to you.

- check out the nbtscan tool that uses netbios to find windows systems
- otherwise you might have a look at broadcasted packets

Unfortunately some overzealous firewalls take it upon themselves to block broadcast pings - and some even block all pings, really annoying.

nbtscan looks like it could be a useful tool, as long as you only have windows machines (and unix machines with samba).

A generic "list all powered-on machines" that works regardless of firewalls might be a bit more of a challenge.
