When you use Point-to-Point Protocol (PPP) to make a virtual private network (VPN) connection that uses both Layer 2 Tunneling Protocol (L2TP) and Internet Protocol security (IPSec), you may receive the following error message after you try to connect to the VPN server:
Error 678 - There was no answer
This problem may occur intermittently after the initial successful connection. For example, the problem may have the following pattern:
Your first attempt to connect to the PPP server is successful.
Your second attempt to connect to the PPP server is not successful, and you receive the "Error 678" error message. You click Cancel, and then you try to dial again.
Your third attempt to connect to the PPP server is successful.
Your fourth attempt to connect to the PPP server is not successful, and you receive the "Error 678" error message. You click Cancel, and then you try to dial again.
Your fifth attempt to connect to the PPP server is successful.
Your sixth attempt to connect to the PPP server is not successful, and you receive the "Error 678" error message. You click Cancel, and then you try to dial again.
This problem occurs because the WinLogon component closes the PPP connection before it closes the VPN connection.
