Cisco VPN Client and Windows 8

I found this while trying to get a Cisco ASA vpn tunnel up.  For some reason the secure mobility anyconnect tunnel would not encapsulate dns or dhcp traffic. This prevented me from being able to access my domain.  I figured I’d give the 64-bit legacy client a try and after the fix below, it worked fine.  Here is what you need to do after you install the legacy client to get it to work.

Hi Everyone,

Just to update, the legacy Cisco VPN client (5.0.07.0440 for x64, 5.0.07.0410 for x86) is working for some people. You need to apply a small workaround as explained below –

 

·    Open Registry editor by typingregedit in Run prompt

·    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 upto “%;” i.e.

o    For x86, change the value data from something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter” to “Cisco Systems VPN Adapter”

o    For x64, 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”

·    Try connecting again

 

Please do revert back if this solution does not work.

 

Regards,

Raman
