alis is trying to read a name server on 'localhost' (Hum, this is
strange, why would traffic to localhost appear on the whire ... well,
it's windows after all. You may want to run tcpdump -n to check the
real IP used). So my guess is that on alis isn't configured to use a working
name server. You should be able to use your ISP's name server; you can also
set up a caching name server on your gateway (I think the default named.conf
does this).
