client-server application

[ask_you]

i want to develop a client-server application where the client application is an executable. whenever the executable starts, it should first contact the server, get validated and only then start. the purpose behind it is to see that only those machines for which the server maintains a list can run the executable. can any1 suggest me some sample code or some suggestions on how to proceed?
