Hi, My question is little bit more complex & needs experts advise. Problem:- We have Windows 2000 Server configured in Native Mode. The domain name that we have does not include my company's name. (i.e it's pdc1.login.com) We have Exchange Server 2003. Now the problem I want to create my domain name as moduleone.com. 1) Is there any Utility or command through which I can change the domain name. 2) What would be the effect on Exchange Server 2003 if domain name is changed 3) Can I migrate the Exchange 2003 from One Domain Controller to another domain controller. i.e on another server to configured as exchange. Please Help me in this matter. ps. check out our latest product: www.DriveInside.com - India's No. 1 Auto Website -------- Amit Kapoor Network Engineer Module One India Ltd.
