You recently been promoted to Network Administrator for DLM Shipping. When you took over this position the first thing you notice is this Windows 2000 environment using DNS naming convention, root domain is DIM.COM, with numerous child domains. User accounts are stored in the child domains. However your supervisor informs you that root domain is misspelled and should be DLM.COM. He explains this is causing tremendous problems with the users and customers. He wants you to rename the domain. What will happen if you rename this root domain server?

• When you rename the root domain server you will only have to rebuild the user accounts since the root domain holds the authentication (SAM) database.
• When you rename the root domain server you will simply rename the child domain also.
• When you rename the root domain server you will lose the entire network orphaning the child domains.
• When you rename the root domain server you will not need to do anything else since domain names are inherited the child domains will acquire the new domain name.
