Also nun zu meiner Frage:
Was muss ich an diesem Quellcode verändern um im Netzwerk die IP, den Namen und den Status eines anderen PC`s herauszufinden?

bedanke mich schonmal im voraus

void __fastcall TForm1::Timer1Timer(TObject *Sender)
{
String ip = IdIPWatch1->LocalIP();
Label1->Caption=ip;

String name = IdIPWatch1->LocalName;
Label2->Caption=name;

if(Label1->Caption == "192.168.0.2")
{
Label7->Caption="Online";
}
else
{
Label7->Caption="Offline";
}
}
