When installing Microsoft’s Exchange 2010, the installation will force you to correct some errors with the system before it will complete. One of these will indicate the error that “The start mode for the Net. TCP Port Sharing service must be set to Automatic before Setup can continue”. When you encounter this error, there is a quick and easy powershell command that you will need to run. To proceed, click on the powershell icon in the system tray of your server. Then run the following command.
Set-Service NetTcpPortSharing -StartupType Automatic
Once run, the setup check will complete the indicated step as intended.
