Changing Subnet Mask in DHCP Scope

[Jeff]

We are currently have the following scope setup on a
network:

146.121.200.x with a subnet mask of 255.255.252.0. We
are going to increase the subnet mask from 255.255.252.0
to 255.255.240.0. I looked to change this in DHCP but
its grayed out. Is there anyway to change the end
address in the range and the subnet mask without deleting
and recreating the scope?

Thanks,

Jeff

No, must delete/recreate. It should only take you a few minutes.....
