hey guyz one of my frnds is planning to open a cybercafe and he has asked my help regarding this problem. he is looking for a software (freeware preferred) that will be able to lock the administrator rights of a system and not let the user mess around with any settings of the OS. The user should be able to download files only in 1 location specified and he should not be able to access the directory of the OS and Program Files. Also he wants that the user cannot turn off the Firewall / Anti-Virus /Anti-Spyware protection at any time while surfing. All the user should be permitted to do is come and surf without losing on basic functionalities and also at the same time not he does not want his pc's to be infested with spyware/porn/adware etc etc. He is thinking of using Win XP Professional as the OS in all systems and he is not going to connect them by LAN. Instead he will provide individual net connections to each machine. Also he requires another software just like the ones used in Sify Iway /Reliance which can be used to create a userid/pw for the customer and then allow him to login , instead of the conventional system of noting down the time for each customer. He wants an automatic software which will deduct the customers balance as he uses his account and will provide facilities of low balance reminders and recharge etc. Something jsut similar to the Sify/Reliance stuff. All your suggestions are welcome and please help me come out with a good secure solution for him.Thanx in advance.
