We have a private Class A NT4 network, with 2 gateways and approx 200 systems. All client systems are DHCP enabled. Everything is fine. Recently, I am wondering if it is possible to configure our only DHCP server to dispense 2 ranges of IP addressese.g 10.70.1.1 to 10.70.2.254 and 10.80.1.1 to 10.80.2.254 in the following manner.

The first range is meant for a specific group of users while the second for another diff group. Each group is supposed to have its own unique gateway; with everything being the same; eg. WINS settings.

I tried but the DHCP server refuses to allow me to set up another scope of diff IP range with the same Subnet mask of 255.0.0.0.

Any advise will be appreciated. Thanks in advance.

You should be able to setup two different scopes, and set the DHCP server to issue the IPs appropriately. Go to Create new scope, and set the range. make sure to exclude the othe ip's from each scope, as well as your static IP's. hope this Helps

The problem is that your subnet is wrong. DHCP will let you set up two scopes... but your subnet is too large and includes both of those scopes already. The subnet 255.0.0.0 includes both the 10.70.X.X as well as the 10.80.X.X ranges. You need touse 255.255.0.0 for each one. The range of your scope is determined by the subnet.
