I am not sure if people are still experiencing this issue but I came across it this morning on my Windows 7 64 Bit system. I eventually figured out the problem... 1. Uninstall Cisco VPN Client 2. Go into device manager and remove ANY Cisco Virtual Adapters 3. Re-install For what I could see the problem was caused by the cvpnd.exe (Cisco Service) process being unable to target a 'single' adapter. Hope this helps anyone having this issue.
