Error connecting to VPN Error 651 The modem or other connecting device has reported an error
While I moved from Windows 7 to Windows 8.1 and got
stuck with this error connecting to office VPN from home.
Tried googling and applied different solutions but could not
successfully fix this VPN issue.
where as I have checked with new VPN credential still I was able
to connect from one of Windows 7 machine but not from this Windows 8.1 machine.
This is the error I was getting – Image – 1
Finally I was thinking to reconfigure the machine. I found Virtual Box is installed in this machine and respective Virtual Network adapters installed in the machine.
Thinking of this might causing the issue I just uninstalled all those shown above in Network Connections page.
Then I restarted the machine and now VPN connects like charm …
I just conclude here the VPN issue I was facing is not something related to OS (Windows 7 or Windows 8.1)
As Virtual Box was there installed and its respective Virtual Adapters were there… it was throwing the above error…
