I am having a network of 50 pc connected to Windows Server 2003. All the workstations in the network has Windows XP installed on it. Now the users here have rights to install applications. I want some help to disable that. I want them to use only those software that I had installed. I had seen people installing additional browser with proxy add-ons to access blocked website. I want some help to prevent the same. How can I do this.
