Failed on two Readiness Checks items with Exchange 2010 SP1 installation: Organization Prerequisites and CAS Prerequisites (see the screen shots)
Then I was trying to run the following cmd to fix this issue:
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
But kept getting the following error:
Install-WindowsFeature : ArgumentNotValid: The role, role service, or feature name is not valid: 'NET-Framework'. The
name was not found.
Can you tell me what is missing please?
