The Windows logon process has unexpectedly terminated.


  • Hello,

    I always get The Windows logon process has unexpectedly terminated error and then my windows server 2008 hangs up! 

    after checking the event logs I found that the last log was  

    Event ID 4005 - The Windows logon process has unexpectedly terminated.

    I updated BIOS,  then I moved the harddisk to another physical system still same problem. :(  

    I then changed the harddisk also ... still same problem :(   I used tuneup utilities 2013 to repair all registry errors ..

    I don't have any bad sector on HD

    registry is totally fine ! 

    at the time of freezing CPU usage was 2% and RAM 9%   (  I have 16GB DDR3 RAM,  Intel xeon E3-1270 Processor )

    I haven't installed any special third party software other than popular ones like firefox, chrome, Internet download manager,  VlC, filezilla and few others.. 

    I have windows server 2008 standard x64  ( and updated too .. no more updates are available )  

    my system keeps freezing at random 

    help me :( plzzzzz

  • Hi,

    Thanks for your post.

    Please ensure the server has all latest update installed. In addition, try to boot the serve with clean boot, to check if the issue still persists. Please also check the event viewer to verify is there any related error showing up. For more detailed steps of troubleshoot Event ID 4005, you may refer to the following article. Hope it helps.
