Windows 10 remote desktop session

I'm trying to connect to my work computer using remote desktop. I have physical access to both. I am getting the following error:

your computer could not connect to another console session on the remote computer because you already have a console session in progress.

I have rebooted both machines. I was RDP'd into it earlier fine. But now it thinks I already have a session. Shouldn't it just connect me back to my session like Windows Server does? Any ideas?

Are you trying to connect to the remote computer by using the hostname or the IP address?

Try:

Ensure that you're on the Windows 10 desktop.
Right click on the start menu and choose Command Prompt (Admin) from the menu.
Type in the command ipconfig /flushdns

I was trying to log in using the hostname. "ipconfig /dnsflush" did notwork. But when I logged in with the IP address instead of hostname it worked. Thank you.
