their is a question i came across which i understand but i dont understand how it would happen
this is the question
You are the system administrator for a large enterprise. You have five servers running Microsoft Windows Server 2003 and 1,500 client computers on the in-house network. You also have 250 users who connect their laptop computers wirelessly to the Internet through your network. The laptop users are salespeople who are only in the office for a brief time. The laptop computers have computer names and are set up to be members of a domain on the network.
The Dynamic Host Configuration Protocol (DHCP) service has been installed on one of the servers. All computers will be configured to obtain an IP address from the DHCP server.
You are configuring the DHCP server to lease IP addresses to the laptop computers and in-house computers. You need to maximize the performance of your DHCP service.
i under stand about creating 2 subetnets for inhouse computers and but i dont understand about how the laptops would connect to the subetnet you created for the laptops and use that address range unless you made it static but what would be the point in that
this is the explaination of the it
By setting up a scope for the laptop computers and a separate scope for the in-house client computers, you will be able to set different lease durations for laptop and in-house computers. Since the laptop computers are not part of the network for very long periods of time, you should make their IP address lease durations short. That way, IP addresses and system resources are freed up. You can ensure that the laptop computers receive addresses from the correct scope by creating a separate subnet to which the laptop computers connect and defining the DHCP scope for the laptop computers with addresses that are valid for this subnet.
The default value for client computer address lease duration is eight days. This value is desirable for computers that are stationary on the network (in-house computers). This reduces the number of DHCP requests and results in lower network utilization. The value of two days is too short for IP address lease duration for the in-house computers.
An IP address lease duration of two days is desirable for the laptop computers that are connecting wirelessly. Since there could be many different laptop computers connecting over time, you will need a larger number of IP addresses available for assignment. By setting the lease duration to a low value, IP addresses can be reused more frequently. Lower lease durations are also desirable for client computers that are connecting through Remote Access.

Two network cards. You would create a vlan with all your wireless access points on, and one with all your normal switchgear, connect one to each card, and configure a subnet for each vlan with different lease times.

DHCP classes (i think.. I'm not Microsoft)

i've never used vlans before only see 1 guy set them up and he was a bit of a pro...so how would you configure a dhcp scope to bind to a network card so it knows or like you say configure the scope to lease the address for you but to me that wouldnt make sense and pointless as you want the dhcp server to do it for you

i just seen somthing on our dhcp server their is a thing called server bindings i take guess you select which network card you would want to use for each scope yea ?

I've never done it personally, but that's the theory yes.

its dhcp classes if its an ms exam.

why is that ? what do you mean

How to Create a New DHCP User or Vendor Class
its a marker that tells the cmoputer which subnet to pick up from.
30th October 2008, 10:27 AM #10
so if i create a vender class say
wireless and desktop
and i made 2 different ip ranges for 2 different different subets. yea DHCP will check the name of the client vender and depending on what its it will assing the right ip address to the right vender
sorry if i seem just got into work and im not with it at the moment i feel like i dont get paid enuff to come into work when its holiday time for schools

Nono, vendor classes and vlan subnets are two different ways to solve the same problem. With vendor classes, you tell each computer 'you belong to class x' or 'you belong to class y'. Then tell your DHCP server the same information, assign a scope to each class, and when a workstation requests and address it gets one from the appropriate pool depending on its class.

so if you set up 2 vlans say 1 = switchs ( goes to hard wired computers ) and vlan2 for all switchs with are assiciated with an AP you would setup 2 scopes 1 for vlan1 which is for computers and a second scope for vlan2 which would be for laptops
