After you install the MS04-003 security update that is described in Microsoft Knowledge Base article 832483, you may not be able to start your computer. Instead, you may receive the following error message:
The Logon User Interface DLL Msgina.dll failed to load. Contact your system administrator to replace DLL or restore the original DLL.
This issue may occur when your TEMP folder, as specified by the TEMP environment variable, is encrypted.
The installer that the MS04-003 security update uses extracts its contents to a subfolder of the TEMP folder. If the TEMP folder is encrypted, the update files are not successfully copied to the Windows\System32 folder when you restart your computer. One of the files that the MS04-003 security update installs is required by the Microsoft Graphical Identification and Authentication DLL file (Msgina.dll). The Msgina.dll file is, in turn, required by the Winlogon service.
To resolve this issue, first restore your computer to a working state. After you successfully restart your computer, install the MS04-003 security update by manually specifying a nonencrypted temporary folder.
Note When you successfully restart your computer after you experience the issue that is described in the "Symptoms" section, the MS04-003 security update is not yet installed on your computer.
