Autenticate Access

On Win2000 server and IIS5 we have a password protect search page; we give a different login and password to any users, but we need that any account come from one unique PC. Now the users give login and password to friend and this is not permitted. We need a function that read a serial number of Hdisk or other way, because only one PC have the right to acces. Please a simple solution, not complicated. We invite you to propose your solutions and suggestions. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Win9x/2000 pro and server NT/XP/ME
