Essentially what you're after is an "agent" that will sit on clients 's machine and talk to your server. Does not matter what it's made in - ActiveX, Java, .NET - the task it has is to monitor the hardware and communicate with the server. For that you may use .NET WCF or anything else for simplicity's sake - establish a channel of communication - http, sockets etc - and start talking to the server.
