Today I tried to connect via RDP to one of my Virtual Servers (Windows Server 2012 R2), and I ran into this message : "The remote computer that you are trying to connect to requires network level authentication (nla), but your windows domain controller cannot be contacted to perform NLA. If you are an administrator on the remote computer, you can disable NLA by using the options on the remote tab of the System properties dialog box."
How am I suppose to make that change if I can't even log in to the server? Why only now did this message come up, I've had this server running for months, wth.
