[thelist] Popups too

What are you trying to achieve?

If you want to disable the Messenger service, you can do that via the
Services MMC Snapin. However, this does not secure your computer in any
meaningful way. Instead, you should enable the Windows XP Internet
Connection Firewall to do that.

Disabling NetBIOS over TCP will not stop the Messenger service completely,
since the Messenger service can receive announcements directly via the TCP
port that it is listening on.

Disabling NetBIOS completely may have unexpected side-effects (and you
certainly won't be able to speak to downlevel clients that don't support
SMB), and is probably not recommended unless you know what you are doing.
