Gina.dll is a Windows file that is used in Windows Operating systems (NT\200\XP) to provide customizable user identification and authentication procedures.
The default Windows logon interface may not appear when you boot your PC after installing a third-party program. If you are using Windows XP computer, you may not be able to use the Welcome Screen or Fast User Switching feature.
When you try to enable Fast User Switching or the Welcome Screen feature via the Control Panel, you may receive the following error message:
“A recently installed program has disabled the Fast User Switching and Welcome screen. To restore the features, you must uninstall the program. The following file name might help you identify the program that made the change: <DLL Filename>”
Note: The <DLL Filename> in the above error message varies and points to the DLL of the third-party program you have installed. For instance, if you have installed Cisco Systems VPN Dialer Program, the <DLL Filename> will be csgina.dll.
Cause of the Error
The above issue occurs when a third-party program replaces the Microsoft Graphical Identification and Authentication file, which is Msgina.dll.
To fix the issue and restore the Fast User Switching and Welcome Screen, perform the following steps:

Malware programs, such as viruses may also delete or modify the msgina.dll string-value in the registry and prevent Logon User Interface from loading. This may cause a DLL error message to appear when you start your system. This is why it is imperative that you keep your system safe from malware. We recommend you install robust antimalware tools, such as STOPzilla Antivirus and Spyware Cease, and schedule regular malware scans of your entire system.
