Check computer availability over network
Take a look at this code for a ping:
http://groups.google.com/groups?hl=en&safe=off&ic=1&th=2468fe4eade11f...
and reduce the timeout to whatever your liking...
If you're having problem on the "name resolution" side of things, you
could perhaps take a look at these registry keys which should reduce
the time it takes for tcp to fail off:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
DWORD Values:
TcpMaxConnectAttempts = 1
TcpMaxConnectRetransmissions = 0
Good Luck,
