you should set the security to tls on 2012/2012r2 and win8/win10 clients, 2008r2 should work with RDP security,
but what i see in the log is that guacd does not connect to your client at all i think - did you FQDN or IP on client config ?

Only guacd actually deals with the RDP protocol at all. I think there are three tomcat logs: localhost_access_log.2016-11-12.txt, catalina.2016-11-12.log, localhost.2016-11-12.log I've reviewed them and I don't think they have anything interesting in them, but if necessary, I'm happy to provide them. For now, I see this in /var/log/messages: Nov 12 11:44:37 tryx guacd[974]: Protocol "rdp" selected Nov 12 11:44:37 tryx guacd[974]: Connection ID is "$97c2d73f-3ec3-4a5f-93b8-71d55fec7576" Nov 12 11:44:37 tryx guacd[974]: No security mode specified. Defaulting to RDP. Nov 12 11:44:37 tryx guacd[974]: Loading keymap "base" Nov 12 11:44:37 tryx guacd[974]: Loading keymap "en-us-qwerty" Nov 12 11:44:37 tryx guacd[974]: Failed to load guacdr plugin. Drive redirection and printing will not work. Sound MAY not work. Nov 12 11:44:37 tryx guacd[974]: Failed to load guacsnd alongside guacdr plugin. Sound will not work. Drive redirection and printing MAY not work. Nov 12 11:44:42 tryx guacd[974]: Error connecting to RDP server Nov 12 11:44:42 tryx guacd[974]: Connection did not succeed Does this exchange offer enough information to diagnose anything, so should I send more logs? I should probably restate: I have three Windows 7 clients that connect with no problem; this problem is specific to Windows Server (2008r2 and 2012r2). I think I have removed the NLA restrictions from these two servers, meaning if I haven't it is due to ignorance, not neglect. I should also restate that I can connect to these severs with the xfreerdp client, so required functionality is present and not blocked by security measures. -- Chris.
