Ok so I'm trying to remove a number of my systems from our Nessus scan from having this medium vulnerability.

http://www.nessus.org/plugins/index.php?view=single&id=18405

I set the following GPO setting:

Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Require Use of Specific Security Layer for Remote (RDP) Connections: SSL (TLS 1.0)

Once I do this my Windows 7 clients no longer have the Nessus problem however RDP no longer works from Linux or Windows clients. I get the following errors:

From clients:

Linux:

[ryan@gobo ~]$ rdesktop -0 win7
Autoselected keyboard map en-us
ERROR: recv: Connection reset by peer

Windows:

"the connection cannot proceed becuase authentication is not enabled

One the server system (Windows 7 box running RDP):

Log Name:      System

and this one:

Description:
A fatal error occurred when attempting to access the SSL server 
credential private key. The error code returned from the 
cryptographic module is 0x8009030d. The internal error state is 
10001.

I've seen solutions on this being a permission problem with the cert, as in the Network Service account doesn't have permission to access it but I can't find where the cert is on the filesystem to check it.

Other than that I'm out of ideas/options. I look for the wise here.
