A. Microsoft doesn't ship Windows 2003 with NetBEUI and doesn't support the protocol in the OS. However, if you require NetBEUI, you can install the version supplied on the Windows XP installation CD-ROM in the \valueadd\msft\net\netbeui subfolder. Copy the nbf.sys file into the \%systemroot%\system32\drivers directory, copy netnbf.inf into the \%systemroot%\inf\ directory, then open network connection properties and click Install to add NetBEUI.
