Stopping Messenger Spam
If you’ve received some anonymous messages popping up on your windows XP or 2000 systems, it may be messenger spam, people are taking advantage of the messenger service that allows administrators to monitor servers and send out service messages over corporate networks. Friends of mine have been complaining about it, but now that we know where it’s coming from, we can stop it.
Open the Control Panel, and then double-click Administrative Tools icon and then double-click the Services entry. In the list of services listed in the resulting Services dialog box, locate the messenger entry, and double-click it. Click the Stop button in the service status section and then in the same dialogue box, change the start-up type to Disable. If you are on a corporate netwrok, check with your administrator before making any changes, and if you are behind a firewall, at work, or at home with some of the cable/dsl routers, then you probably won’t have to worry about it at all.
