winxp,sp3,ie8,nis2012       same here but error code 8504,104 autofix wanted me to run norton power eraser, also said something about internet connectivity-host file cleanup.   now when i come to norton forum i get the yellow triangle with ! mark in bottom left done but error on page. i did not run power eraser, just shut down unit for 5 minutes, booted back up and no problems other than error on norton forum page.
