I am aware of the option under the advanced tab in RDP client 6.1 that will disable a prompt for an invalid certificate. Is there any way to disable the prompt for all users? I have two terminal servers that my users can only get to through proper authentication. From there, many of my users RDP into other servers on the network. Because these terminal servers are Server 2008, they have the RDP 6.1 client. Is there a registry hack for this or do I have to generate certificates for every RDP-enabled server on my network?
