DHCP Scope options

[xKhai]

I'm really stuck and hoping someone will have some insight as im clueless..

Currently right now im working on a project to create a DHCP server that will have 3 different scopes for VOIP, PC/LAPTOPS, and wireless VOIP phones.

Each of these devices have different lease times.
VOIP - 3 days
PC/LAPTOPS - 30 Days
Wireless - 10 Days

So far i have created 3 different scopes all on the same subnet mask. The part where i'm stuck is getting each device to go to their corresponding scope. All these devices just go to the first available scope for an IP.

I think it has to do something with defining User class's but i dont know how to specify it towards each device or implementing it on the scope.

The OS platform is Win 2000 server.

Any help will really be greatly appreciate!!!

Scopes should be created based on Networks not Type of device.
For example:
Scope 1 = 10.0.1.X/24
Scope 2 = 10.0.2.X/24
Scope 3 = 10.0.3.X/24

DHCP will know which address to give a client based on which network the 'request for IP' comes from.

Okay, if i base the scopes of that...how do i get the devices to receive IP's from the different scopes rather then just the first one?

In my example, If you place the device on one of those three separate networks (Subnets) they will get IPs from the Address Pool configured for that scope.

Okay, if i base the scopes of that...

You really can only base your scope on networks, that is the way MS DHCP was designed.

Here is the link to MS DHCP home page.

Base on what WhoKilledKenny recommended:
Carve out 3 VLANs on the switches the devices are connected to. Assign the ports to a specific VLAN based on what kind of device is connected.

There are other ways to do this, but it depends on what kind of switches you have. Some can dynamically assign VLANs dependent on MAC address, etc.
