I have a basic Windows 2008 terminal server that I have installed my wildcard Comodo certificate on to try to rid my users of the annoying certificate error when they connect via the RDP client. Unfortunately, it is not working. The certificate in the error message has definitely changed from the self-generated one to the *.domain.com cert that I installed, but Windows is still throwing a fit because it does not match the hostname that the users must enter to access the host. Do wildcards work in TS 2008? I don't have TS Gateway or Web App set up, just a plain jane 2008 Terminal Server.
