I set all the group policies I could find to stop students from changing their background. All is fine with windows explorer and Internet explorer, users can't change their background. But if they use Firefox then they can right click any image within a web page and "set as desktop background" which will bypass all group policy and set it as a background, only until next log on. Any help how to stop it? Thanks

Thanks for all reply, in case I didn't make my self clear I would like to have a public calendar that doesn't show the time as normal e.g. 10:00 , 10:30, 11:00 ... But Period 1 8:45-9:40, period 2 9:40-10:35 and staff can select when they are using the ICT rooms easily. Thanks

Hi, I would like to create a shared clander for booking ICT rooms. But instead of it appearing like a normal exchange calendar I would like it to be just as our lessons periods. Lesson 1, 2, ... Has anyone know how to do it? Thanks
