I have a few computers on my network, about 60 out of 1000 desktops. These computers have started randomly taking about 40 minutes to present the user with the "press ctrl +alt + delete" section. PCs display a message about applying a GPO that does not exist. The GPO refers to applying disk quotas, after troubleshooting i can confirm that there is no GPO applying that or GPO by the name that is being displayed.
If i remove this PC from the network, (Unplug Network Cable) the same issues persists.
Any Pointers are welcome.
