This post discusses an issue we have found with the FNCW and Exchange 2007. The symptom is that you receive the following error when running the Internet Address Management Wizard:

“The wizard cannot configure Exchange e-mail for your domain. To correct this problem, run the Fix my network task on the Connectivity subtab of the Network tab of the Windows SBS Console.”

However, when you run the FNCW to fix this issue, it fails and you receive the following error:

“The server cannot connect the SMTP connectors. Ensure that Exchange is running, and then try again.”

You will notice that none of the SMTP connectors in Exchange have been fixed as a result.

There are two possibilities that will cause this behavior:

  1. The Default ServerName receive connector is missing in Exchange at the time that you run the FNCW.
  2. The Default ServerName receive connector’s Authentication and Permissions Groups settings are wrong at the time that you run the FNCW.

NOTE: Replace ServerName with the hostname of your SBS 2008 server.

To resolve this issue, use the Exchange Management Console to either manually create the default receive connector or correct the authentication and permission group settings for the existing one. Afterwards, the FNCW will successfully fix your SMTP connectors.

To create a new connector:

  1. In the Exchange Management Console, expand Server Configuration, Hub Transport, Receive Connectors
  2. Click on New Receive Connector in the Actions pane
  3. Name the receive connector default Servername where Servername is the hostname of your server.
  4. For the intended use for this Receive Connector, choose Custom.
  5. In both the Local and Remote Network settings windows, accept the defaults
  6. Once its created, open the properties of the receive connector
  7. Under the Authentication tab, enable Transport Layer Security (TLS), Basic Authentication, Offer Basic authentication only after starting TLS, Exchange Server authentication, and Integrated Windows authentication

  8. Under the Permission Groups tab, enable Exchange users, Exchange servers, and Legacy Exchange Servers

  9. Rerun the FNCW from the SBS Console.

When correcting the authentication and permission group settings for an existing connector, follow steps 7, 8, and 9.
