I work at a school and we are having issues with the student profiles. For some inexplicable reason that we have been unable to resolve for almost a year, random students are logging in and unable to access the Internet. This only happens if the clock is displayed in the bottom right corner of the Taskbar! If a student logs in and the clock is not there, as it should not be, then all is well ... if they login and the clock is there then there are a multitude of problems including internet access. We've all but given up trying to work out this weird quirk but we do have a work-a-round. If we delete the user profile of the student and get them to login again then all seems to be OK! My question is, can anyone tell me how to use group policy to automatically delete the user profile of the student when they logoff, this was every time a student logs on to any PC or Laptop it will be as though it is the first time they have used that device and they may solve our problem. Please keep in mind that deleting the user profile at reboot is not the answer to this problem as 95% of our computers are left switched on but logged out!
