DHCP and Win7

Hi !
Did you :
- try to disable the win7 built-in firewall
- verify that DHCPdiscover are initiated from this machine
- check that there are some DHCPoffer seen from this machine interface

Could you just launch a capture with wireshark on "Adaptador de Ethernet 
Conexión de área local", initiate a "ipconfig/renew *"
then wait 5 seconds, stop and save capture file and mail us the file.

Best regards
