when i expand default-first-site-name -> servers -> there is a domain controller that has been demoted and is no longer apart of our domain. when i expand the properties of the old domain controller there is a folder listed called 'exchange settings.' when i click on 'exchange settings' in the right pane i see 'active directory connector (servername)' listed. if the server is no longer apart of our domain and has been demoted is it safe to just right - click and remove the server from active directory sites & services ? this may be an odd question, but i wasn't around when that domain controller was online so i am not familiar with its properties, etc. any insight would be greatly appreciated.
