Disabling Messenger Service

Microsoft has included a service in the last few versions of Windows that allows system administrators to send pop-up messages to all computers on a local network. This service can be an invaluable resource for administrators who want to get the word out about some upcoming server maintenance. For example, end users would see a message pop up on their screens that notifies them that the work group file server will be inaccessible for the next hour while routine maintenance is performed.

This is a great service n when it is used correctly. Unfortunately, the Messenger Service has been abused. Just because any user can send messages to the entire work group doesn't mean that she or he should. This capability is sometimes not a good thing. Users that are part of large local area network, such as just about every Internet user, can send out a mass message to all users in the same subnet. As you can imagine, some users that know how to use the service have started to
abuse it by sending spam to all the users in their same subnet. Nowadays, you may get spam not only in your inbox but also in a pop-up window that could appear at any time.

The Messenger Service, just like any other service or program that is accessible to the outside world, increases your security risk. Although there is currently not an exploit for the Messenger Service that allows remote users to execute commands on your computer, who knows what the future will hold? To be safe, it is best to just disable this service. You will also be cutting down on a new type of spam.

Disabling the Messenger Service can be done by using the Service Manager. Follow these steps to get started:

1. Click the Start button and select Run.

2. Key in services.msc in the box and click OK.

3. The Services Manager will load. Scroll though the list and right-click Messenger and select Properties.

4. Change the Startup Type to Disabled.

5. Click the Stop button and then click OK to save your changes.

Now the Messenger Service is one less thing to worry about. You can kiss the annoying pop-up text ads goodbye and also reduce your risk for an attack in the future.
