I am getting many errors in the event log similar to:
Failed to apply IP Security on port VPN0-34 because of error: A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate.. No calls will be accepted to this port.
I look at the Certificate Store for the local machine and there are no certificates. Could this be the problem and how to fix it.
I have a SBS 2003 domain that I am adding 2 Win2012 DCs that will someday replace the 2003. One 2012 server has a couple of certificates in its local store. The other one doesn't and is getting the above messages. Both 2012 servers are fresh; I can remove and start over if this is a serious problem.
Its not serious problem. If you are using servers as windows L2TP VPN servers, then you must install Computer (Server) certificate on both servers and computer certificate on client computers, otherwise these steps are not necessary
You have to have internal CA server at least to provide certificates.
