789: The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer

Cause: Your operating system is not correctly configured to connect to an L2TP server. The connection attempt is failing before a connection to the server is ever attempted. This error is caused entirely by a misconfiguration of the user's operating system. Location, or connect type has no bearing on receiving this error message.

Solution:
Windows Vista
Open Control Panel >> Administrative Tools >> Services
Make sure the IKE and AuthIP IPsec Keying Modules service is started and configured to start automatically at startup. If the service is already started, restart it.
Make sure the IPsec Policy Agent service is started and configured to start automatically at startup. If the service is already started, restart it.
Attempt to connect to the VPN server again, if still unsucessfully, please contact the Helpdesk and notify them of the takes you have already taken to resolve the issue.
