After having big delays in trying to install the correct pre-requisites. Not matter how many times I uninstall and re-install IIS, Exch 2010 is not happy with it…
1: Import-Module ServerManager
2: Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,RPC-Over-HTTP-Proxy -Restart
3: Set-Service NetTcpPortSharing -StartupType Automatic
Use the above in power shall (admin rights), and this will simplify.
