I had a similar problem. I solved it by downloading and running “IIS Manager for Remote Administration 1.2” and doing a “Repair” operation. This did three things: 1) reduced the startup time for the IIS Manager dramatically, 2) added a “Start Page” root node in my IIS Manager Connections pane (I know this used to be there but I had not noticed it was missing after my Windows 10 update), and 3) fixed my remote connection node.
