The server is just a simple IIS box - no AD DS or anything else, running Windows Server 2012 with the latest updates applied.
If I RDC to my server using the IP address it connects without a problem.
If I set up a host name like server.mydomain.com to point to the IP address and use this within RDC then I get an error "The user account is currently disabled and cannot be used." - even though I am using the same login credentials.
What difference does using a host name have as opposed to an IP address to connect via RDC? And how can I change it so I can use the hostname as well as the IP.
It should be noted I do not have this problem with Windows Server 2008/R2.
