Chris-thanks for the tip. I had tried that in the beginning with no result, but here's what we eventually found out. ON the new installation of TS 2008, when we installed a SSL cert, it automatically bumped up the security to the SSL level form the client compatible level. Once we returned it to the client compatible level we were OK. But...I had to restart the PocketCloud client once or twice on each device before it would connect.
Thanks for your help
