Network Access Protection - Why is my computer restricted?


If you have already connected to the Thomas network this year, access may be restricted for one of the following reasons:

  • You have not restarted your computer in a long time. (If you have been away from the campus network with this computer and it also has not been shut down and started back up since the last time it was on campus, the Microsoft Windows security service network access protection service may no longer be actively scanning your machine. In this situation, you may not be able to connect to the Internet, and your computer may not tell you why it cannot connect.)
    • Restart the computer.
  • Windows has not been restarted after recently installing an update that requires a restart.
    • Restart the computer.
  • Windows has not checked for updates recently or has not installed all critical security updates.
