This topic explains how to resolve Exchange Server 2007 Service Pack 1 (SP1) setup failure on the Hub Transport role because of an incorrect fully qualified domain name (FQDN) configured on a receive connector.

The installation of Exchange Server 2007 SP1 may fail on the Hub Transport role with the following error message: "When the AuthMechanism parameter on a Receive connector is set to the value ExchangeServer, you must set the FQDN parameter on the Receive connector to one of the following values: the FQDN of the transport server "", the NetBios name of the transport server "server", or $null."

The FQDN on the receive connector does not match the internal FQDN of the Hub Transport server.

When the authentication mechanisms on a receive connector include Exchange Server Authentication, the FQDN on that receive connector must match the internal FQDN of the Hub Transport server. Otherwise, authentication will fail causing the internal mail flow between Hub Transport servers to also fail. To prevent this situation, Exchange 2007 SP1 setup checks these settings on the receive connectors and then stops if it detects this condition.

You must change the FQDN on the receive connector to match the internal FQDN of the Hub Transport server.

If you do not want your Hub Transport server to display its internal FQDN in response to HELO or EHLO, you must create a custom banner. For more information about creating custom banners, see How to Modify the Default SMTP Banner.

To perform this procedure, the account you use must be delegated the Exchange Server Administrator role and local Administrators group for the target server. For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

  1. Open the Exchange Management Console.

  2. In the console tree, expand Server Configuration, and then click Hub Transport.

  3. In the result pane, select the Hub Transport server for which you want to configure the receive connector.

  4. In the work pane, right-click the receive connector that you want to configure and then click Properties.

  5. In <Receive Connector> Properties, select the General tab.

  6. Type the internal FQDN of the Hub Transport server in the Specify the FQDN this connector will provide in the response to HELO or EHLO field.

  7. Click OK.

  • Run the following command to set the FQDN of the receive connector Default Server1 on Hub Transport server to the FQDN of the Hub Transport server:

    Set-ReceiveConnector -Identity "Default Server1" -Fqdn ""

For detailed syntax and parameter information, see Set-ReceiveConnector.
