DHCP Server - Allocating different gateway IP

Dear Sir/Mdm

Can anyone please advice me how to go about getting the DHCP server in
Windows 2003 Server to allocate different gateway to different user.

Eg, I have 2 broadband lines (512kbps & 1.5Mbps)and 2 routers.
Router A IP : 192.168.1.254 (for 512Kbps)
Router B IP : 192.168.1.253 (for 1.5Mbps)

Can anyone advice how to configure DHCP server to allocate the IP address of
Router A (192.168.1.254) as the gateway to computers in Finance Department
and allocate the IP address of Router B (192.168.1.253) as the gateway to
computers in Operation Department.

Simply, I just need to have 2 different department to access the Internet
via 2 different gateway.

If DHCP function in Windows Server 2003 is not achievable, is there any
other workaround?

Thank you in advance

DHCP can't knows which computer is in which group.
So you would have to use mac reservation (with two scope, with a different
gateway).
I would better, if possible put everyone one the 1,5M, and add the 512 as a
secondary default gateway.
So if the main one is unavailable, all your computers will use the other
one.
(this is also true even if you keep your split)

Dear Mathieu CHATEAU

Can I conclude that the DHCP in Windows 2003 does not catered for load
balancing?
Is such case, is there any 3rd pary solution that can resolve such issue?

Please advice.

DHCP has never been meant to do load balancing...

To achieve what you want, you may use linkproof appliance (or other), that
will use both link and distribute traffic based on state & utilization.

When the computer ask for a lease, the dhcp server only have the mac address
as client information.
The Mac address isn't store in Active Directory, and therefore cannot be
used to filter hosts.

I recommend you this setup:

One big scope (IP Range) with everyone:
2 default routes (first the small, then the big link as failover)

One small scope (IP Range) with IT dept:
2 default routes (first the big, then the small link as failover)
->Reservation by mac address.

Looks like I have to assign static IP for one of the department.

Once again, thank you for clarifying the DHCP server is incapable of
performing such tasks & scenario.

It took me a while to search online, only your site unfold the fully details, bookmarked and thanks again.
