Common DLL Errors  -Msgina.dll     

User Interface Failure:
The Logon User Interface DLL msgina.dll failed to load.
Contact your system administrator to replace the DLL, or restore the original DLL.

This error occurs on machines using the Windows 2000 operating system. Specifically, it occurs if you use Windows 2000 with Service Pack 3 installed. More recent service packs and older service packs do not encounter this problem.

This error occurs when you first log on to your computer, because several DLLs and executable files that are dependent on one another attempt to start at the same time. If the files start in the wrong sequence then you will receive this error.

In order to resolve this error users should download the latest Windows 2000 service pack, because this error is not present in any apart from version 3.
