RDP to Server 2008 credentials always fail initially

When I attempt to RDP from a Windows 7 box to a 2008 Terminal Server, I always get a prompt that "Your credentials did not work". "The credentials that were used to connect to TS1 did not work. Please enter new credentials.".

I then enter my password and it connects fine. If I tick "Remember my credentials" they aren't remembered and I have to type my password each time.

It's teh same for a RemoteApp on the terminal server too. I just want to double click the app shortcut and open the app but I have to enter credentials each time.

Please can someone suggest how to either get my password to be remembered, or to automatically use my logged in credentials?

I'm on an AD domain.

Have entered my username in the format DOMAIN\USERNAME and have also tried username@domain.

Are you the admin of this TS? If not, there is a GPO that can be set by the admin not allowing passwords to be remembered.

Yes, I am the admin.
For RDP connections to the server, ensure the RDP-Tcp tab 'Log on Settings' are set to 'Use client-provided log on information' and the 'Always prompt for password' checkbox is not selected. You will find this under the RD Session Host Configuration role on the Terminal Server.

For RemoteApp Single Sign-on, Windows 2008 R2 is required with a public CA certificate installed in IIS7, RD Gateway Manager, RemoteApp Manager and RDP-Tcp 'General' tab. See this site for more on RemoteApp Single Sign-On http://blogs.msdn.com/rds/archive/2009/08/11/introducing-web-single-sign-on-for-remoteapp-and-desktop-connections.aspx.

Thanks ITAS01 - the settings were Ok in the RDP-Tcp properties sessions tab.

However on the general tab I changed Security layer from 'Negotiate' to 'RDP Security Layer' and I no longer need to enter credentials to start an RDP session.

Although you didn't get the answer spot on you certainly helped to zone me in on a solution - thanks for that!  Will give you some points for your help.
