SYMPTOMS
When you establish a dial-up connection to the server by using Integrated Services Digital Network (ISDN), and then you try to establish a virtual private network (VPN) connection, you may receive the following error message:

Error 651: Your modem (or other connecting device) has reported an error.



CAUSE
This problem occurs because the Layer 2 Tunneling Protocol (L2TP) tries to create a host route and then detects that the route to the host that was created by the dial-up connection already exists.
