This sounds like MESSENGER SERVICE
Windows Messenger Service windows may appear when using Windows NT, 2000, or XP online. They have nothing to do with the similarly named MSN Messenger chat program or with your web browser (so any popup stopper option has no effect).
Windows Messenger Service was designed to enable messages to be sent over a Local Area Network (LAN). Typically, a system administrator might use it to notify users that the server is about to be shut down. Because it uses the same TCP/IP communication standard as the Internet, such messages can also be sent over the Internet.
Turn off the Messenger service. To do this, follow these steps:
1. Click Start, and then click Control Panel (or point to Settings, and then
click Control Panel).
2. Double-click Administrative Tools.
3. Double-click Services.
4. Double-click Messenger.
5. In the Startup type list, click Disabled.
6. Click Stop, and then click OK.
