  You can try to manually change it and see if it helps. Is this is a new build of Exchange?

  Set-ADServerSettings -PreferredServer dc2.contoso.local

  Is that DC still showing in AD? Check ADSI Edit and delete it from there. Are there event logs on that exchange box referring to 'AD Topology'? This should explain what DCs Exchange is able to speak to or not able to speak to inside and outside its site. Have you rebooted the Exchange box since the demotion?

  Hi,

  Please make sure you are running Get-ADServerSettings in Exchange Management Shell instead of Windows PowerShell in Exchange server.

  Additionally, please do the following steps to select a specific domain controller for Exchange server:

  1. Open Exchange Management Console in Exchange 2010.

  2. Expand Microsoft Exchange On-Premises.

  3. Right-click Organization Configuration, select Modify Configuration Domain Controller.

  4. Check Specify a domain controller and  click Browse to select the Domain and the DC.

  5. Click OK to save the configuration.

  Regards,
