Is MRVGINA.DLL Must to Establish Wireless Networking?

MrvGINA.dll is a graphical identification and authentication dynamic link library file that Netgear requires when installing their wireless card drivers. When establishing remote desktop connections by using any wireless networking products by Netgear, the MrvGINA.dll file is a must-have in your system.

With the earlier release of this dll file, there were some Windows User Management issues, as the MrvGINA.dll disables Fast User Switching. Many who were using Netgear wireless networking products faced this problem and had to revert to the default msgina.dll (provided by Windows/Microsoft for the same purpose as a default in the system), and later either reinstall the original file or wait for the fix and download it from Netgear itself.

There are some very common errors occurring in Windows, in relation to the dll file.

•    After installing a new type of driver for your network and you reboot the system, the normal Windows logon screen will not appear.
•    When you are trying to establish a Remote Desktop Connection, you get an error message saying the MrvGINA.dll is incompatible.
•    Rebooting after installing a new driver, the error message “cannot find MrvGINA.dll, contact administrator” comes up.

For all three of the above common errors, there is one correct answer with two ways of achieving the same result. Actions such as deleting the driver and trying to reinstall will only make matters worse. The proper solution involves registry editing and should be done so at your own risk.

How to Rectify the Errors

Method 1:

Restart your computer. Login to your system and from the Start menu, select Run and type regedit. When the registry opens, navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/Current version/WINLOGON and delete the key named GINAdll. Then, go to the Control Panel/User Accounts. Here, select Change the Way Users Logon and Logoff. Enable “Fast User Switching” and apply changes.

Method 2:

Restart your computer. If your Windows logon screen does not appear, try booting through Safe Mode by pressing F8 continuously before the Windows logo appears. Once in Safe Mod, follow the same steps in Method 1.
