When opening an app in RDWeb (running on 2008 R2) I am getting a pop up stating that "your remote desktop connection failed because the remote computer cannot be authenticated" on my XP SP3 machine - not a problem in vista, win 7. It is advising me that there are problems with the security certificate. It looks like a name mismatch. The requested name is TS.domainname.ca, and the name in the certificate is TS.domainname.local. The error is encountered when validating the computer's certificate; "The server name on the certificate is incorrect" If I change the authentication level:i:1 level to 0, i dont' get the prompt, but I am not thinking this is a valid or secure solution.
