The best approach for this is to create a Multi-threaded COM Server .DLL for your server and make it a COM+ application. You will also have create a proxy .MSI file (from the COM+ app) and install it on each client. All this can be done in Window Component Services.
In your client code, create an object reference to the server .DLL and make your calls.
