Windows Client Choose between 2 DHCP servers in the same lan.

Question

I have two DHCP in the same network. One with IPs 10.0.0.0 and the Other 192.168.0.0. How do I configure my windows XP to choose between one of them.

Thanks

Answer 1

As I understand DHCP, the client will use whichever one responds first.

Which could be a problem.

Edit in response to the new post down below:

The ideal solution would be to separate the two companies LANs via a bridge/brouter with one DHCP server on each of the local sides. Presumably, the brouter would also route packets not destined for either network to whatever Internet router you currently have,

Answer 2

Unless you're doing something clever, I would consider it a bad idea to have two DHCP servers on the same LAN.

Can't you disable one?

Answer 3

Multiple DHCP servers on one network/VLAN is BAD - it will cause all sorts of issues with your network, especially if one is "unofficial" - ie, handing-out addresses even though it's not supposed to.

Answer 4

You don't. You should remove one of those DHCP servers from your LAN.

I can't think of a good reason to have 2 DHCP servers offering 2 different scopes on the same LAN. If you really need, this, you probably need to setup reservations so on both so addresses are only delivered to the correct hosts.

Answer 5

The problem is that in the building we have two companys but we share the same internet connection. One company have one scope and the other company have another. I need to set my company's computers to one DHCP.

Please HELP, thanks

Answer 6

Setup your DHCP server to serve the addresses based on MAC adresses, mapping one-on-one or each MAC to an IP range.

Or try to configure each machine IP statically.

Answer 7

Hi All,

If you have configured the two DHCP server in same network, then how to diffrentiate from system get the IP from which DHCP.

Then you can define through the Routing helping address. Add your DHCP IP in routing helping address according to lenth of users.

you can add the DHCP server IP in routing helper address according to V-Lan, which is configured in department, process, or domian wise.
