Troubleshooting the Microsoft Exchange Transport Service When It Fails to Start on an Exchange 2007 Hub Transport Server with Event ID 1032 or 1036

Event ID: 1032 Socket Access Denied. Binding: 0.0.0.0:25.
Event ID: 1036 Failed to open one or more bindings. The service will be stopped.

This issue occurs when the Internet Information Services (IIS) Simple Mail Transfer Protocol (SMTP) service has been installed on the server and is running.

To resolve the problem, remove the SMTP service.


On Exchange 2007 servers, the Network News Transfer Protocol (NNTP) service and the SMTP service are no longer required.
