Bill one of my fully awesome students from this week’s 10135 class ran into this issue after our first lab today. The installation appeared to be a success but after trying to launch the Exchange Management console all he saw was a can’t connect error message due to WinRM not being able to contact the server via HTTPS. We checked the IIS bindings and saw all was in place, as were the necessary services. Bill discovered if you remove the WinRM IIS extensions and then re-add them via server manager resolved this. Great troubleshooting Bill!
