Logon User Interface Failure

[Guest]

Mine is Windows XP Home Edition. When I boot my computer,
I cannot open my windows, and it just appears little
window and says,

"Couldn't find Msgina.dll....User Interface Failure,
please call the administrator or replace the original
DLL."
And then there's only a "re-boot" botton, and I cannot go
to safemode for repair...someone please help me, thank
you.

This sounds as though you have tried to change the Boot/Logon Screen. Risky
business.

There are other causes/reasons but with those one is able to boot into safe
mode to correct. You may have to resort to the Recovery Console.

Info on the former:

The msgina.dll (Graphical Identification and Authentication dynamic-link
library) should be listed in C:\Windows\System32 - Application extention.

This can happen if you installed PCA, VPN Cisco Client, etc. Normally
removing any of the above, the msgina.dll is replaced.

Check here for gina.dll, ginamsi.dll, or CSwgina.dll if either is listed,
remove it, reboot.

Start/Run/Regedit
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Current Version\WinLogon.
In the right pane, remove the entry for (XX)Gina.DLL.

Or...

Restore the Windows XP Welcome Screen (Gina.dll) Line 45
