I need help in setting up the DHCP Service on SBS 2000 Server. Specifically the Scope Option that hands out the subnet mask to the client workstations. I utilize a class B network (172.25.x.x). The server hands out the IP addresses okay, but then the work station appears to default the subnet mask to 255.255.0.0. I would like the DHCP Server to hand the workstation a SM of 255.255.255.0. I would think this might be a Scope Option, but I cannot determine which one it is. I see a couple options like "Perform Mask Discovery" and "Mask Supplier Option", but I'm not sure if either of these is what I am looking for. I would experiment, but I don't want to distrub the 40 users who are presently logged in. No one is having any trouble, but I can't ping the work stations remotely and I think this is the reason.
