reason 442: failed to enable virtual adapter on windows 8

After installing Cisco VPN Client Windows 8 64Bit you get the error reason 442: failed to enable virtual adapter when trying to connect.

Solution:

  • Open regedit
  • Browse to the Registry Key HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\CVirtA
  • Select the DisplayName to modify, and remove the leading characters from the value data up to the last “%;”
  • for 64 bit; change the value data from something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows” to “Cisco Systems VPN Adapter for 64-bit Windows”
  • for 32bit; change the value data from something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter” to “Cisco Systems VPN Adapter”

Reboot to test, the above solution worked for me on Cisco client version 5.0.0.07.0240 64bit.

Password Recovery Procedure for the Cisco VPN 3000 Series

The following method does not make you lose the configuration on the concentrator so far tested.

The factory default passwords for the Cisco VPN 3000 Series are:

username: admin

password: admin

Complete these steps in order to recover a password:

  1. Connect a PC to the VPN Concentrator with a straight-through RS-232 serial cable between the console port on the VPN Concentrator and the COM1 or serial port on the PC. Use software such as Putty  to connect to console.

    When the Concentrator boots, and after the power-up diagnostics check is complete, a line of three dots (…) appears on the console, a sample of which is shown here for reference. Press Ctrl-C within three seconds after you see these dots. This displays a menu that lets you reset the system passwords to the defaults.

  2. Boot-ROM Initializing...
