This morning end-users reported they were not able to get to their desktops right after their first log in. It only affects those end-users that shut down their computers last night. So, when they logged in this morning all they got was a login prompt> then a blue screen> nothing else. This did not affect folks that locked their computers. This is affecting 3 different cities and all of our servers and network equipment looks ok. We are working with Policy Maker Software, but we do not know if that is the cause. How do we find out. We have no error messages on the DCs or PCs.
