I'm working with two different networks:Ethernet LAN in a 172.19.0.0/22 network
(work) and Wireless in a 192.168.2.0/24 network (home).

For testing purposes, I activated preferences->name resolution->resolve network
(IP) addresses in my home network. Since then, if resolve network addresses is
activated, wireshark uses the home dns (192.168.2.1) server and not the
dns-server which win7 uses (172.19.3.32, checked with ipconfig /all). Option
use an external network name resolver is checked. The problem is reproducable.
