RDP connection does not work since yesterday when connecting via VPN:
Network Level Authentication (NLA) is required for the remote computer you are trying to connect to. However, NLA cannot be performed because the Windows domain controller cannot be reached.
There are no problems in local network without VPN.
Turning off NLA helps, but is not a permanent solution for security reasons.
Is it also related to Microsoft update as described here?
UCS: 5.0-4 errata740
