Wget don't resolv hostnames?

[Orestes leal <orestesleal13022@cha.jovenclub.cu>]

Hi Folks, I ran wget in my system but when i try to get one file
for example


"""" wget --server-response http://www.server.com/fichero.xml
--14:15:06--  http://www.server.com/fichero.xml
           => `fichero.xml'
Resolving www.server.com... """""


""And stays there with this message.
Resolving www.server.com... failed: Temporary failure in name resolution.""

Where server.com it's a fake url in this case of course,
I'm behind several subnets so my configuration it's these:


I have a router, 1 dns server, 1 proxy that resolves all requests
from the users, so my question is:

What kind of configuration I must make?



NOTE: my /etc/resolv.conf actually holds my dns server and the graphical 
browsers works good, so any help?
