I had tried all combinations with Vista Firewall and Network Settings
(Private, Public, turning the firewall on and off, etc. etc..) Disabling the
service was kind of "last chance".
I found out what's going on after all. When I renewed the IP's on XP
machines, they just sent DHCP REQUEST, and get ack by the DHCP server. VISTA
sends a DHCP DISCOVER packet, that the DHCP server (it's a DLINK DSL-500G)
seems to ignore. Without response, there's no DCHP REQUEST, and thus no IP
from the server.
I searched DLINK's website, and found no firmware upgrade for my modem. So:
Is there a way to disable the "DHCP DISCOVER" on VISTA's TCP Stack? Or am I
left to manually set IP's on VISTA machines?
