Hi Fajar,

on the Linux DHCPD I would add an "allow" directive to the pool, and put your 
LTSP clients in a class:

subnet 10.0.0.0 netmask 255.255.255.0 {
  ....
  class "ltsp" {
    match if ...
  }

  pool {
    ...
    allow members of "ltsp";
  }
}

Afaik W2K DHCP does not have such an option - so you could probably try to fill 
the W2K DHCP address range with reservations, so that it does not have any more 
IP addresses to serve for other clients that you want. But I did not test that, 
so YMMV...

You said you have to have your W2K server running - but couldn't you just 
disable the DHCP-Server on it and serve all your clients form the Linux DHCPD? 
Recent versions of dhcpd also support dynamic DNS registration, so I don't see 
any (technical) reason why to keep the W2K DHCP...

Just my 2c,

Subject: [CentOS] 2 DHCP server in one subnet

Hello all,
In the network there is already a W2K server serving as DHCP server for the 
network. Then we want to implement LTSP, so we need to setup another DHCP 
server, right?

Due to unexpected reason (little by little migration of w98 clients to LTSP), 
we need to keep the W2K server running in that network. Can we then have 2 DHCP 
server in the same subnet, only serving pre-determine clients using mac 
address? Any clue on how to setup the dhcpd.conf?

Thank you very much.
