Unable to connect to my Windows 2003 Server Standard

I have Windows 2003 Standard Server and I have been using RDP to remote into the server.
Now, when I connect I get an error message “The remote session was disconnected because there are no Terminal Server License Servers available to provide a license” Please Contact the server administrator.
I do not have any licenses for Terminal Server or any other servers on my network.

Is there any way around this? Can I just uninstall Terminal Server? Will I still be able to remote in? I might have maybe 2 people rdp in at once.
