When installing Windows Vista using an unattended file, the computer name entered during OOBE is not used to join the domain.

After you use Windows Vista to change the name of a computer, other computers can continue to access the computer by using the previous name of the computer.

When this issue occurs, the following conditions are true:

• If you clear the Domain Name System (DNS) cache by using the ipconfig command together with the /flushdns switch, this issue still occurs.
• If you change the network adapter at the same time that you change the name of the computer, this issue does not occur.
