Hello,
I am having an issue with thin clients on my new RDS configuration. All Windows 7/10 etc instances of MSTSC connect to RDS fine. I have some Thin clients previously configured to 2003 Terminal Services that need reconfiguring to 2012 RDS.
I receive the error when trying to connect "Because of a Security error, the client could not connect to the remote computer".
In the Server event logs under RemoteDesktopServices-RdpCoreTSOperational, I see that it logs on and then an Event ID 103 "The disconnect reason is 0"
I have ensured that "Allow connections only from computers running Remote Desktop with Network Level Authentication" is NOT set, but I still receive the error. I am not sure where to look next. I read on Technet that possibly a cert is corrupt, but other Operating systems connect with no issue.
My set up is one collection with one server and I am attempting to connect directly to the FQDN of that one server.
If I have missed any details out, please let me know. Any help gratefully received.
Many thanks,
Dan
