Guacamole connected, waiting for response for a while then disconnected

Hi,
I have this problem with Guacamole. After logging in, I got a message saying Guacamole connected, waiting for response and after about 15 seconds, it disconnects. 
This problem only happens with few workstations(no matter what browser was used), not all. I works very well with other workstations that I try so I guess I have configured Guacamole correctly. 
Can anybody help me out?
ThanksHung

Hi Hung, I can confirm Guacamole works with Windows 7 RDP just fine. Did you enable RDP under the system properties? See screenshot. http://prntscr.com/b9i08r  Also make sure windows firewall (on the desktop) isn’t blocking tcp port 3389.       From: do hung [mailto:dohung1970@yahoo.com]

Hi,

My Guacamole can work with RDP for Windows server 2012 but it doesn't work when I connect to Windows 7. Is there any difference between Remote desktop on Windows server and Windows 7?

Thanks

Do you see anything in the Tomcat logs from Guacamole around the time that
a user attempts to connect and fails?

I highly recommend using a proxy rather than running Tomcat as a privileged
user for the sake of port 80, and even MORE highly recommend using SSL [1].
This can be addressed later though.

As for the problem at hand, is there any proxy at all between the affected
workstations and your Guacamole server? Perhaps the kind of virus-scanning

Only the publicly-facing port used by Tomcat (or the proxy in front of
Tomcat) need be open.

Typically, this will be 443 (HTTPS), with a proxy like Apache or Nginx
providing SSL termination and avoiding the need to run Tomcat as a
privileged user.

If SSL has not been configured at all (not the best idea, but common when
people are just getting started), then this will probably be 8080 -
Tomcat's default port.

Can you tell me which firewall ports should be opened in order for Guacamole to work? 
And for your information, those workstations can do everything else just fine, no internet restriction at all(youtube, facebook..etc)
