Hello,
I’m trying to use rdpsign.exe on Windows Server 2008 to sign an rdp connection file.
Command line like this:rdpsign /sha1 82BF48CF5BE3F8A2275D3C1B7CBA18E501802EB3 remote.rdp
I can generate remote app files from the RemoteApp Manager, and sign those files using this certificate through the RemoteApp Manager gui. However when I use the rdpsign.exe utility from the command prompt, specify the thumbprint for the same cert (which is correct, I get an error saying cert not found if I put in an incorrect thumbprint), and then specify the .rdp file I want to sign I get the following error:
Unable to use the certificate specified for signing. Error Code: 0x80090010
The rdp file could not be signed. Error Code: 0x80090010
The certificate being used is an imported .pfx file of an InCommon cert generated for FQDN of the server. As I said it’s working for generating signed remote app .rdp files on the same server, and is working as the certificate used with TLS for encrypting the actual remote desktop sessions.
