DUNS ERROR 781

781 - The encryption attempt failed because no valid certificate was found.

This error may occur with Windows 2000 or XP client attempting to connect to a virtual private network (VPN) using Layer 2 Tunneling Protocol (L2TP) and IP Security Protocol (IPSec).

If you are not attempting to connect with VPN, L2TP or IPSec, check your Connectoid's Security tab - and set it according to your ISP's instructions (most ISPs use 'Typical - allow unsecured password).

If you are attempting to connect with VPN, L2TP or IPSec:

• There may be a problem with the remote computer:

  The certificate on the VPN server is not valid or missing - the administrator of the remote computer must correct the problem.

  The IPSec Policy Agent service on the remote computer may be stopped, or stopped and re-started without stopping and re-starting the Routing and Remote Access service on the server. The administrator of the remote computer must correct the problem.
