I understand that is it the freerdp package (that Reminna relays on) that is responsible for these failure in negotiation: https://github.com/FreeRDP/Remmina/issues/54

Typically, I'm able to connect to Windows servers if security is set to the default "Negotiate": Remmina > Profile > Advanced > Security > Negotiate However, I'm currently onsite at a company, and I'm unable to connect to their new server that's running Windows Server 2008 R2 Enterprise if I have security set to "Negotiate". I eventually discovered that I can indeed connect if I set security to RDP: Remmina > Profile > Advanced > Security > RDP So I'm reporting this to suggest further testing with the "Negotiate" security feature with Window Server 2008 R2 Enterpise. In my case, it was unable to negotiate to discover that it could indeed connect over RDP. Instead, I had to discover this for myself and set the security manually to RDP.
