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

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

• 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,

• 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?

• 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.

• 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.

• 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

• 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.

• I've got a similar issue, in both that it's unchangable and 
  multi DHCPs.  Below is a map of my network
  
  
  PC3  PC1   PC2
   |    |     |                     Wide_Area_Network
   | DHCP_server_1(Hub)  (Rogers Wireless High Speed,DHCP_server_2)
   |    |                                  |
  Wireless_Client----------------------Wireless_AP
                                           |
  Laptop1(wireless)------------------------|
  Laptop2(wireless)------------------------|         *Dashed are 
  Laptop3(wireless)------------------------|          wireless signals
  
  The point is, all the computers need to be registering their ips 
  to Rodgers.  However, the Wireless_AP is not always turned on, 
  therefore, in order to get PC1 and PC2 to talk to each other, 
  they need to have a DHCP Server.  Unfortunately, when the Wireless_AP 
  is turned on, the DHCP_server_1 still adresses IPs.  (Meaning no 
  internet for hard-wired devices)
  
  Thank you all for your assistance :)
  
  

  Nick Whaley : In some advanced DHCP server, you can configure in a delay. This is for exactly what you need; so that it will give out IPs ONLY if there is no other DHCP server.

• 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.
