Hello, please stick to one thread for the same problem: http://social.technet.microsoft.com/Forums/en/winservergen/thread/b8c9b10d-907b-4235-9850-d25108787c7b And if Exchange 2007 or 2010 is installed in a domain, domain rename is NOT supported configuration. I have no idea if it may work but with all occuring problems you are NOT SUPPORTED by Microsoft.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
