When installing Exchange 2010 you receive “The start mode for the Net. TCP Port Sharing service must be set to Automatic before Setup can continue”

During my lab testing and installing Exchange Server 2010 on Windows Server 2008 R2 I keep receiving this pre-requisite that fails.

The start mode for the Net. TCP Port Sharing service must be set to Automatic before Setup can continue.

As far as I know (I might be wrong) this pre-requisite only fails the readiness check on Windows Server 2008 R2. In order to set the Net.TCP Port Sharing Service to Automatic at start-up do the following:

  1. Open Power Shell on the Windows 2008 R2 Server that you are trying to install Exchange 2010.
  2. Type: Set-Service NetTcpPortSharing -StartupType Automatic
  3. Hit enter.
  4. Run the Exchange installation wizard again and you should be good to go.

A good idea is to run the cmdlts on each of the Exchange server roles before you start installing Exchange 2010 as per this Microsoft article.
