Using REG.EXE, built into Windows XP, Windows Server 2003, and later operating systems, or installed from the Windows 2000 Support Tools, and InterfaceGUID.bat, I have scripted EnableNBT.bat to retrieve or set the NetBIOS over TCP/IP setting for an interface.

The syntax for using EnableNBT.bat is:

EnableNBT Name Action Setting


Name    is the name of the Local Area Connection.                              Action  is an R to retrieve the NetBIOS over TCP/IP setting, or a W to write it.                              Setting is the name of a variable that will contain the NetbiosOptions if Action is an R or                                      if Action  is a W, the name of the variable that contains:                                              1 - NetBT is to be enabled on the interface, or                                             2 - NetBT is to be disabled on the interface.
EnableNBT.bat contains:
