Well the title of this post is obviously general but if your computer is not a Domain Controller I can’t say that this solution will work for you as well. I got this issue on my Primary Domain Controller based Windows Server 2008 and it was restarting again and again before Login screen, there was Mouse Pointer and Black Screen before restarting. Well I rectify this and troubleshoot this error in steps below;
Step 1:- Press F8 and Boot in “Last Known Good Configurations Mode” (Not work)
Step 2:- Press F8 and Boot in “Safe-Mode” (All options tried but it continues same behavior)
Step 3:- Press F8 and Choose “Disable Automatic Restart on System Failure Option”. It gives below blue screen with following text.
STOP: C00002e3 Security Accounts Manager Initialization failed because of the following error: A Device attached to the system is no functioning. Error Status: 0xc0000001. Please Click OK to shut down this system and reboot into Safe Mode, Check the Events log for more detailed information.
