Sometimes we have to use this below command to use rdp to our old server 2003 domain.
mstsc /v:servername /admin
I have ubuntu desktop with Remmina and i can use normal RDP login for most of the time using Remmina gui.. but when i need to disable Remote Desktop Services client access licensing and force login, I use above command.
I'm not sure Remmina can do the same or do I have to use a different client or this is impossible. Just wish to take advice, please help. I've tried googling and found this, but not found exact thing what i look for.
