Hi Mike, | Are those servers perhaps configured to require NLA? | https://technet.microsoft.com/en-us/library/cc732713(v=ws.11).aspx
| If so, you would need to either configure the RDP servers to allow non-NLA | connections, or configure Guacamole to use NLA, which will require specifying | the username/password in the connection parameters: | http://guacamole.incubator.apache.org/doc/gug/configuring-guacamole.html#rdp-authentication | I believe Windows Server 2012 may additionally require that all connections use | TLS, so if things still don't work there, explicitly specifying "tls" for the | security mode in the connection parameters may help. If the cert used for TLS | cannot be verified (ie: it's self-signed), you may also need to set | "ignore-cert" to "true". Thanks very much. This is very helpful. I'll investigate each of these points and report my results. -- Chris. V:916.974.0424 F:916.974.0428
