Why cause csgina.dll problems in winxp

Cisco Systems VPN Dialer requires the Csgina.dll file for the correct function of the VPN program.

Note This issue that is described in the “Symptoms” section of this article may also occur when you install other third-party programs that replace the Msgina.dll file.
