The problem I described is that the Windows machines in question are not 
necessarily dedicated web servers, but can be regular dial-in users. 
Normally, such users don't run a web server over dial-up, yet they seem
to be vulnerable if the attack occurs while they're connected. No relation 
to the connection bandwidth was implied.
