I'm having some trouble installing this dhcp relay agent service. When I open Network properties, Services, Add, the mentioned service does not appear as a choice. At first I thought that maybe the Gateway E-3110 OEM version of NT left this out on purpose. I spoke with there support people, and they stated that even there non-OEM version did not display this service.
We have 30 new systems which all do not show this service. They all have sp3 & TCP/IP.
