DHCP and Win7

Tue Feb 26 15:29:41 UTC 2013

Well, I assume the trouble here is Win7. But, why? That's my question. I
don't understand why Win7 isn't asking the DHCP server for an IP address.
(Or maybe is the DHCP server the trouble? I don't really understand it,
that's why isn't so clear my question)

I'm trying to collect information in the network between my Win7 test
machine and the server. The network is dead, I haven't received any
information. And I'm renewing all the connections in Win7 (ipconfig /renew).

BTW, I tried with both ethernet interfaces for the IP information (I
configured the server on eth0 and eth1), without good results. I dunno what
else can I do. Do you have any ideas?
