I have a 2 server domain. My primary File Server is also my domain controller. It is running Windows 2008 32 bit Server. My other server is running Windows 2008 R2 with Exchange 2010. My clients are all using Outlook 2010. Forever the internal domain has been xxx.local and the external domain is yyyyyy.org. When running Exchange 2003 this never created any significant issues. After migrating to Exchange 2010, I quickly discovered the issue with SSL Certificates not being issued for .local domains anymore. I did purchase a Certificate for the external domain do users have no issues there. The internal users can use Outlook 2010 but get regular and annoying messages about a certificate mismatch error because of the xxx.local domain.
Is there an easy way to rename the domain without having to basically wipe and reload exchange after a domain rename? Everything I read says domain renames are not supported if Exchange 2007 or Exchange 2010 exist in the domain.
