Default Behavior

The Netbt service is a kernel mode driver. If Netbt fails to start, the error is recorded into the Event Log. Windows Vista startup proceeds, but a message box is displayed informing you that the netbt service has failed to start. At least one service depends on Netbt. Therefore I do not recommend you to disable it.


The Netbt service won't start, if the following system components are stopped or disabled:

If Netbt is stopped, the TCP/IP NetBIOS Helper fails to start and initialize.
