Privacy leak while surfing

[Kai Kretschmann <K.Kretschmann () security-gui de>]

Hi,

A small privacy leak seams to occur while surfing with IE in a local LAN.

I noticed a lot of netbios name service broadcast from different windows 
workstations for name resolution requests of various webserver names. It 
seems that the IE tries to resolve normal internet domain names using local 
netbios ways in addition to the configured DNS.
Now I can all see surfed domain names with the requesting client IP without 
spoofing anything, simply watch the broadcasts coming along.
