01. Database is store in NT Server I want to Develop a Server Service that Run on NT server and it respond to all client request.
In this way network speed will go up because when user request a Record that is bottom one all records data travel from Server to client in this way all network application speed go down.
02. I also want to tight the security that Server Service Application have full Access but normal users have no permission to Database.
Sound like a good place for building a COM+ Component in VFP. You can have your COM+ Component impersonate a security roll in NT without having to give rights to other users. Your users will have to make all request through your COM+ Component.
Maybe you can give some more details about the application scenario to better understand your needs.
