RDS 2012 Single Sign On

Capture.JPGI have a single server RDS 2012 deployment. The server has all roles, RD Web Access, RD Gateway, RD Connection Broker, etc. When I open the web interface and login, I can launch my published apps with no issue. When I configure a computer to connect to the RDWeb feed it connects no problem but I am prompted for credentials. I added the GPO to enable the delegated credentials and it went from giving me just a simple credentials popup to the attached. If I enter the credentials, it works fine. I'm using a Digicert single name cert. I have an identical setup at another client and SSO works fine. No prompt. In the event log of the client, under Application and Service Logs, in the TerminalServices-ClientActiveXCore i get the following errors:

RDPClient_DTLS: An error was encountered when transitioning from TsDtlsStateHandshakeComplete to TsDtlsStateDisconnecting in response to 5 (error code 0x80004005).

RDPClient_SSL: An error was encountered when transitioning from TsSslStateHandshakeInProgress to TsSslStateDisconnecting in response to 9 (error code 0x80004005).

I have looked up both and found little to nothing. Thanks in advance

So I figured it out. I compared the collection settings to my other client that is working and found that the security was set for "low" on the one that was not working and "client compatible" for the one that was. Changed to client compatible and it's all good.Capture.JPG
