When upgrading Exchange 20013 to Service Pack 1, if you have servers running both back-end and front-end roles and you run the front-end Microsoft Exchange Transport service on the server, you might experience the Microsoft Exchange Transport stopping and not restarting.
If you stop the Microsoft Exchange Transport service, you can start the front-end Microsoft Exchange Transport service. Then, when you try to start the Microsoft Exchange Transport service, that service does not start and the following events are logged in the Application log:

Description: Worker process with process ID 18420 requested the service to terminate with an unhandled exception.
This issue occurs if there is a receive connector of Transport type HubTransport that has the binding set to port 25 on the affected Exchange 2013 server. On an Exchange 2013 server that has both back-end and front-end roles, only the FrontendTransport server-type receive connector should have the binding set to port 25.
To fix this issue, run the following cmdlet to change the connector type from HubTransport to FrontendTransport:
Set-ReceiveConnector –Identity "Receive connector name" –TransportRole FrontendTransportAlternatively, delete and re-create the receive connector and set its role to FrontendTransport.
Thank you! I have set a "Relay Connector" for other Servers with Port 25, this has caused the transport service to stop. I almost thought, my exchange server has to be reinstalled (it's a new installation, no mbx on it yet...).
