Remote Desktop Not Working

I have windows a 2003 Server with SP2
Just recently I was unable to use Windows Remote Desktop to access the server as administrator.
When I try to connect I get this message {the remote session was disconnected because there are no Terminal Server client access licenses available for this computer}
When I go to the server I see a popup that reads
{This computer is past its grace period and need to connect to windows server

Can you checlk that your license server has working correctly and has free licenses?
Your trial period for Terminal Server has expired. It has happed to me.

If you do not need Terminal Services and only 1 or 2 people just need access. Then remove the Terminal Services and it will allow you to just  have the Remote Desktop Service that allow up to 2 ppl to use RDC for the server.

If you want to continue to use Terminal Services ; you will need to to buy some Terminal License CALS . contact the vendor you purchased your server from.

you need to go on your server and go into terminal services manager identify what users are logged on and if any sessions are shown as disconnected you need to right click that user and log them off since they did not fully log off of the terminal session.
On client machine
type "regedit" and click ok

navigate to "hkey_local_machine\software\microsoft\mslicensing"
