Just a thought: Rogue DHCP server?<br>

Server logs, will contain info if discover is received.<br>

sniffing at the server to see if any discover packets arrive.<br>

<div>Hello!<br>
Are you sure that your problem lies on DHCP level? Have
you tested the connectivity between windows 7 client and
the dhcp server using static addresses?<br>
</div>
<div>If so and there is connectivity - can you start
sniffer (i.e. wireshark) on Win7, configure it to listen
on an active interface and gather data?<br>

<div>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)<br>
<br>
</div>
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).<br>
<br>
</div>
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?<br>

You started with "unable to send IP
addresses to Win7" but with your<br>
latest info it seems like the proper
question is the reverse: "why<br>
can't win7 send DHCP requests to my DHCP
server?".<br>
<br>
Is Win7 configured to use DHCP?<br>
If you use wireshark or tcpdump on Win7 and
on the DHCP server, do you<br>
see any DHCPDISCOVER from the Win7 machine?<br>

As I said, the logs doesn't show me<br>

Win7 hasn't active the Firewall Service.<br>
