External RDP not connecting to DMZ server on a SonicWALL 4060

I have setup machine in DMZ.  Am able to access web server on machine, ftp to it, ping it, etc...  I can not RDP to the server though externally.  I have Terminal Services TCP 3389 open.  i can RDP internally though.  Any ideas?

If you try to telnet to the server from the outside on 3389 are you able to connect.  Gives a nice baseline to see if the problem is server or FW.

Do you have individual rules?  i.e. one for ftp, web, etc...or all on one rule.     If you have them setup as a individual rule my guess is your rule for TS is botched up some way....I would delete the existing rule and recreate.    
Make sure your RDP rule specifies 'TCP' and not 'UDP'

Maybe just double-check that you have a NAT Policy set up to route Terminal Services (SonicWALL includes both TCP and UDP in this default Service Group) to this host as well as a WAN to DMZ firewall rule allowing Terminal Services to its public IP address.
