Installing the NetBEUI Protocol

Microsoft no longer supports the NetBEUI protocol as part of WindowsXP.

You can add it as a installable protocol by going to the VALUEADD \ MSFT \ NET \ NETBEUI
directory on the CD ROM. 

Note: %SYSTEMROOT% refers to the drive and directory where you installed WindowsXP.
Typically this is in the C:\WINDOWS directory

1. Copy the nbf.sys into the %SYSTEMROOT%\SYSTEM32\DRIVERS\ directory
2. Copy netnbf.inf into the %SYSTEMROOT%\INF\ directory
3. Open the Network connection properties for your local area network and use "Install..." button to add NetBEUI protocol

I included a zipped file with the above files and a simple batch file to copy both to the appropriate directories

This is only if you absolutely need NetBEUI. It is not at all a necessary requirement for most networks.
