Network Level Authentication Error on Windows XP


If you experience the error "The remote computer requires Network Level Authentication, which your computer does not support" when connecting from Windows XP...



You will need to perform the following steps:

  • Apply the latest Windows Updates (incl. XP Service Pack 3)
  • Ensure that the Microsoft Remote Desktop Client is at least version 7.0 [Download Here]
  • Enable Network Level Authentication (NLA) [MS Fix it for me]
