User profile corruption after you lose network connectivity or hibernate a Windows-based computer

Si applica a: Windows 8.1 EnterpriseWindows 8.1 ProWindows 8.1


Consider the following scenario:
  • You log on to a computer that's running Windows 8.1, Windows Server 2012 R2, Windows 7, or Windows Server 2008 R2 and that has Roaming User Profiles enabled for you.
  • You log off, and as your user profile is being uploaded to the server, you unexpectedly lose network connectivity. This may occur if you close the display on a portable computer or by other means of putting the computer into a suspended state such as hibernation or sleep.
  • You restart or wake up the computer.
  • You try to log on to the computer again.
In this scenario, there is a small chance that a file may have been corrupted during the last upload. This might be the ntuser.dat file, and this file represents the user's registry. This could lead to a corrupted profile, and in that situation, you can't log on. Or, the computer may now be in an unstable state.
