In our environment , we have users that work in and out of office. we need to set 2 DHCP scopes , one scope with the lease of 8 days, and this will be assigned to computers that are all the time in the office, another scope will be for laptops that are moved  frequently in and out the office , the lease for this scope will be like for 1 day.

I wonder how to tell a computer when it is plugged to the network and powered on, to which DHCP scope should it get an IP address from.


Thank you.

DHCP servers cannot only react on MAC, but also on vendor class id.
See http://technet.microsoft.com/en-us/library/cc783756%28v=ws.10%29.aspx
for defining it on the clients, and

for using it on the server.

Depending on how many clients, you could give a static to the internal and set a single scope up for the visitors.  The other idea I have is to allow a wireless AP to give a DHCP address using a different scope on the same subnet to laptops.

I am not sure about your architecture and know this isn't really the answer to your question, but maybe it will point you in a different but workable direction.

You need to check it with your network admins for this. I believe they does some kind of configurations on the ports connected to computer so that the computer will get IPs from specific subnet.

What you want to achieve is not doable unless you have a way to differentiate the computers when they boot up or request an IP configuration through DHCP.
Some leads :
- Use different subnets (VLANs for instance. You would then have a different scope)
- Use MAC addresses
