MOM Rule Name

Microsoft Exchange could not register the service principal name.

This Error event indicates the Microsoft Exchange Transport service couldn't register the specified service principal name (SPN).

SPNs are used to support mutual authentication between a client application and a service. The SPN is the same for any method of authentication. When it uses Kerberos to authenticate itself to a server, the client requests a session ticket for the service principal name. When the client uses certificate-based authentication, the SPN is validated against the contents of the "SubjectName" field of the certificate of the server.

This Error event may be caused by an error in the operating system during the DsServerRegisterSpn function.

To resolve this error, do the following:

  1. Determine the description of the Win32 error code that is provided in the event description. To look up system error codes, see System Error Codes at the MSDN Web site for more information.

  2. Use the explanation of the Win32 error code as a guideline to resolve the Win32 error.
