Problem with DHCP

[Guest]

Hi
I can't get proper ip ore dns adress from dhcp. It is working ok with xp and
others but not with vista. When i try to connect vista "generate" their own
ip adress and put a worning that i can have problems with network connecion.

I'm seeing a similar problem.

When I hard code in the IP addr and such the network functions just
fine. When I tell the computer to get its network information via DHCP
it fails to contact the DHCP server.

I've checked the logs on the DHCP server (ISC DHCP server version 3) and
I can see the discover getting to it:

Jun 20 15:51:40 tigana.ccs.neu.edu dhcpd: [ID 702911 daemon.info]
DHCPDISCOVER from 00:0b:db:53:5d:ba via 129.10.118.1
Jun 20 15:51:40 tigana.ccs.neu.edu dhcpd: [ID 702911 daemon.info]
DHCPOFFER on 129.10.118.215 to 00:0b:db:53:5d:ba via 129.10.118.1
Jun 20 15:51:40 tigana.ccs.neu.edu dhcpd: [ID 702911 daemon.info]
DHCPDISCOVER from 00:0b:db:53:5d:ba via 129.10.118.1
Jun 20 15:51:40 tigana.ccs.neu.edu dhcpd: [ID 702911 daemon.info]
DHCPOFFER on 129.10.118.215 to 00:0b:db:53:5d:ba via 129.10.118.1

But the client (Vista beta 2) never recognizes that it gets a response.

I'm getting the IP just fine for Vista from ISC dhcpd - Do you have
authoritative; set in your dhcpd.conf?

My setup has an caching DNS in my LAN and I'm using it for all the DNS
queries and forwards. And my dhcp addresses are reserved strictly for
"guest" machines - Dhcpd setup is as follows:

# Start of dhcpd.conf
# Set the IP ranges, lease times and domain names according
# your actual setup
option domain-name "sub.mydomain.org";
option domain-name-servers 192.168.25.1;

default-lease-time 600;
max-lease-time 7200;
authoritative;
ddns-update-style ad-hoc;
log-facility local7;

subnet 192.168.25.0 netmask 255.255.255.0 {
range 192.168.25.200 192.168.25.225;
option routers 192.168.25.1;
option broadcast-address 192.168.25.255;
default-lease-time 600;
max-lease-time 7200;
}
# End of dhcpd.conf
