On the one hand you can use NetServerEnum
( http://www.pinvoke.net/default.aspx/netapi32.netserverenum )

On the other you can scan your subnet by merely trying to connect or sendinf ping messaga...
To issue ping on specified host you can use IcmpSendEcho win32 function
( http://www.pinvoke.net/default.aspx/icmp/IcmpSendEcho.html )

Thank you for the info, i will try it out and let you know how it went.

The first method failed for me, i guess it expects a real 2000/2003 server to
be on the network?
I have 2 workstations(WinXP) hooked up together, i don't have any real
server running if you will.
the second method is nice, except i'm confused if i am looking at the
internal network IP's or the internet IP's. lol

Is there any way to do something like:

IsServerRunning("ServerName"); (Returns a bool)
isComputerON("ServerName"); (returns a bool)

something simple, i mean explorer lists available computers on the network,
why can't this be easy to do.
