If your getting the above error and system is restarting try the following:

To enable internet connection firewall, do the following
Open Internet Explorer -->
Go to TOOLS Menu
Select CONNECTIONS tab
Select the Service provider, Click on the SETTINGS button
In the window that opens, click PROPERTIES button
Go to ADVANCED tab
Check the INTERNET CONNECTION FIREWALL checkbox
Click OK


If you already have a firewall in place this shouldn't be an issue.

Seems to be only affecting XP. Also, make sure you download all the latest patches from MS update site.
