Hello ,
I hope you can help me to fix this issue, it's been 5 days since I a, trying to configure VPN in your 2008 and 2012 Servers. On both platform (2008 and 2012) I am getting same error while configuring VPN (after role installation).
"Unable to load C:\Windows\System32\iprtrmgr.dll". So, I have removed IPv 6 entry from the registry and now able to start server (not sure what configuration it took automatically). I tried to disable "Routing and Remote Access" service and got the same error while enabling "Routing and Remote Access" is running but VPN is still not functioning properly).
I am getting following error,
================================================
