The EMC and PowerShell on the passive node of my CCR cluster do not work correctly. I can open both tools but I'm constantly getting the error "Unexpected Error -x6C87A79F wile executing command <command>. When I launch the PowerShell and run \(GET-EXCOMMAND).count it only returns 141 commands. My active node returns 394. Is there a way to re-register the missing commands with Powershell?

Found the solution... somehow the snap in for the EdgeTransport server was configured in the registry on my passive node. See the following thread for details. http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/895fee15-e135-4a90-a2bf-bf7d73acf813/
