Hi guys,
Let me explain the situation,
I had two DCs with Ad replication, one was a 2003 sbs and the other was a 2008 R2 running
A 2003 domain function and a 2000 forest function level.
The 2003 held all the FMSO roles.
I got rid of the old 2003 server yesterday, transfered all the roles successfully to the other DC
Demoted the 2003 server successfully and rasied the domain function level up to 2008 R2
I also raised the forest function level up to 2008 R2, I did this all without any problems. :-)
My next task was to get the vpn working on the 2008 R2. So I turned on routing and remote access. Then I get this on the event viewer in server manager.
Event id 20171 failed to apply ip security on port VPN2-0 becuse of Error: A certificate cannot be found. Connections that use the L2TP protocol over IPsec require the installation of a machine certificate, also know as a computer certificate no calls to this port will be accepted.
So im stuck as I cant find much info on this?
I have checked the firewall on the router and made sure that ive changed the ip addresses so that the vpn will pass through.
Not sure what I need to do when it comes to certificates? Any help is much appreciated
Thanks Mcat2013
