"Failed to access NetBT Driver - NetBT may not be loaded" error message when you run the nbtstat command in Windows XP or Windows Server 2003

When you try to run the nbtstat command with a command-line switch such as nbtstat -a remotename in Microsoft Windows XP or in Microsoft Windows Server 2003, the command does not run. Additionally, you receive the following error message:

This issue occurs because users without administrator rights, including power users, do not have sufficient permissions to run nbtstat when the user includes a command-line switch.

To work around this issue, use one of the following methods:

• Use a user account that includes administrator rights to log on to the Windows XP-based computer or on to the Windows Server 2003-based computer.
• While you are logged on as a user without administrator rights, use the run as command to run as a user who has administrator rights. Then run nbtstat.

The nbtstat command displays the status of current NetBIOS over TCP/IP connections, updates the NetBIOS name cache, and displays the registered names and scope ID. It is by design that users without administrator rights cannot use the nbstat command with command switches.
