I have a home network that I am setting up. I have a linuxbox running both my LAN DNS and my LAN DHCP. For some reason my XP machines are not seeing the LAN correctly. When I checked my connection settings on the XP machines they were recognising the DHCP server WAN address not the specified LAN address. THis is causing them not to correctly identify machines in the LAN.
Can anyone give me a little infor on what I may have setup incorrectly.?

How is your network setup at home? Does the internet come through a home router and then to your other computers? Remember that DHCP cannot span routers unless they are setup properly (which in most cases you don't want anyways). Routers, by default, discard broadcast packets, so, as soon as it sees a DHCPDiscover packet or any other DHCP packet, it drops them. So, your clients should be on the same segment of the network as the DHCP server.

I have Everything attached directly to the Router. It used to act as my DHCP server till I wanted to add a better LAN DNS for my computers. I disabled DHCP on the Router and let my Pri Linuxbox take over the job.

Physical Address: ****************
IP Address: 12.1.1.104
Subnet Mask: 255.255.255.0
Default Gateway: 12.1.1.1
DHCP Server: 12.1.1.7
Lease Obtained: 2/22/2005 10:44:16 AM
Lease Expires: 2/22/2005 10:44:16 PM
DNS Servers: 12.1.1.7, 24.116.209.232, 24.116.0.202
WINS Servers: 12.1.1.7, 24.116.209.232, 24.116.0.202

The DHCP line above - DHCP Server: 12.1.1.7
usually comes up as DHCP Server: #WAN address#
