Since I upgraded to 12.04, I am unable to RDP to a Windows 7 server. All I can see is a pop-up that says "Uable to connect to RDP server ". I am able to RDP using Vinagre, so that rules out any issues with my router or the Windows server.
As far as I can tell, there are no logs from Remmina and the Debug window shows a blank.
Any one got any ideas?
Thanks.

Make sure port 3389 is opened on your firewall and router.
In Remmina edit your connection, click the "Advanced" tab and choose RDP under the "Security" option and save.
I have no idea why it worked, but I started changing settings one at a time. When I edited the connection properties, I looked on the "advanced" tab and changed the security from "negotiate" to "TLS", and voila, everything works.
Strangely, "negotiate" still works on the laptop, but at least I'm back in business with my bigger monitor :)

I too had the problem that I could connect to a Windows 7 machine and suddenly (after weeks) I got this error: Unable to connect to RDP server
In my case I deleted the entry from ~/.freerdp/known_hosts and it then worked fine.
