Last Friday 13th, a lot of WinXP SP3 computers on our environment never display the desktop for the users, except when the user is part of the Local Admins Group. Also events 4609 or 3100 were generated at the app log.On other computers the desktop appear to the user, but there were no network connections,I found that disabling the GPO inheritance at the OU where the computers are located resolved the issue.Does someone has an idea of wich settings could create such situation.andresz1 person needs an answerI do too
