Can someone tell me how to add options 15 for domain suffix? My Dhcp

server does not have options 15 listed for selection. Under Global
Preferences, I have a options to add but again when I go to add
I don't have options 15 listed. Can it be done and what I have to do
add? We are changing our domain name and I need to push out the new domain name under domain suffix for all windows client (W2k, W98, XP).

I am running DNS/DHCP 3.11f on Netware 6.
