So I got nailed today on my laptop by the messenger/netsend spam technique. It is really nasty. From tech/tv, here's an explanation of the netsend facility:
What is this messenger service and why is it spam? The easiest way to explain it is to show you the ethical and non-ethical ways of using the messenger service. The ethical use turns the messenger service into a handy tool for system administrators. They can monitor servers and send out status pop-ups if a problem occurs. See an example by clicking here.
I really should install a firewall. In the meantime, I'm shutting down the messenger/netsend service tonight so that hole will be closed. From techtv here's how:
To turn off the messenger service in XP:
- Click on the Start button and open the control panel.
- Open the Performance and Maintenance control panel and go to Administrative Tools.
- Now double-click on Services, then scroll to Messenger.
- Double-click Messenger and click Stop to stop the service.
- Change the startup type to Disable (see an example).
