the company that i work for is setting up 1 machine with windows 7. this machine will have an active server webpage displayed constantly. users that are authorized will be able to utilize the workstation, but the office we have has other businesses that sublet office space. we want to attempt to keep these tenants from using the machine for personal browsing. while assigning a global password would secure the ws itself, i am attempting to find something slick....this will also give people another reason for us all to upgrade to win 7. any ideas?
