Hi

If you mean messages from the Messenger service:

You should follow the recommendations in the MS Knowledge Base article 330904,
from http://support.microsoft.com/?id=330904 :

"For this reason, Microsoft recommends that you install a firewall and configure

it to block NetBIOS traffic instead of merely just turning off the Messenger
service."

So what you should do is to block internet access to ports 135, 137-139 and 445
with a firewall.
