Tell me about it! I get them about once a week. It's bad enough that they invade my inbox, but I'll be danged if they're going to invade my desktop! I know I can disable Messenger Service, but have not done so because it is not recommended by Microsoft. Here is what they have to say about it: "...If the Messenger service is stopped, messages from the Alerter service (notifications from your antivirus software, for example) are not transmitted. If the Messenger service is turned off, any services that explicitly depend on the Messenger service do not start, and an error message is logged in the System event log. For this reason, Microsoft recommends that you install a firewall and configure it to block NetBIOS and RPC traffic instead of turning off the Messenger service." My ISP also recommended that I get a firewall and specifically Norton Internet Security for Virus and Firewall protection. I have to update this weekend, so I may as well give it a try. If it doesn't work, then I will turn the blasted thing off regardless of what Microsoft says. Thanks for the feedback on Poser :)
