Hi,

I'm dealing with a situation where there are 2 DHCP servers involved. One is local and the other one is remote (behind routers). The remote one is used for redundancy purposes. Presumably, should the local DHCP server fail, the local users would get their IP address from the remote DHCP server.

Converse to what we expect, the local clients are getting their IP address from the remote DHCP server instead of getting it from the local one. The local server is active, the clients have been rebooted and they keep receiving the IP addr from the remote site.

My question is:
- How the priority between several DHCP servers is handled, since the whole process starts with a DHCP Broadcast ? 

- Would it be possible to "force" the clients to go first to the local DHCP server rather than to the remote, without introducing parameters on the client ?

Thanks in advance,

guy
