XML-RPC Communication with a Windows Service

I'm working on a system for my workplace that can track offending users in a computer lab. I have a system in place to track users (what their login name is, and vnc terminals available). This system uses a Windows Service to gather information about users logged into the lab computers. It responds to a master program running at a front-desk machine with a one line response containing the data about user sessions, etc. However, I would like to have a web app (WordPress plugin) be able to query these lab machines through my service installed on them to: obtain screenshots, send message popups (because net send is blocked on the network), and maybe more features to come.

The protocol I'm using is this:

1. Front Desk sends out a UDP packet with a single word rollcall
2. Lab Machines respond using TCP-connect back with data about user sessions
   • Packet response: <machine name>;ROLLCALL;<username>;<domain>
   • Packet reponse(alt): <machine name>;<username>;<domain>;<table number>

However, I'm not sure if I should be querying like this from the web. I'd prefer to try something like XML-RPC communication, but I can't 开发者_如何学Cfind any examples of how to accomplish this in a Windows Service Application (non-ASP.NET).

Does anyone have any recommendations? I'd prefer an XML-RPC protocol because I'd like to experiment and learn XML-RPC.

You can use WCF to create a "web service" that runs on the each system. XML-RPC is like Remoting that was used for .net 2.0 Nowadays we use WCF since its more powerful. You can check Microsoft's documentation about remoting for more info.
