No need for a DHCP server? Just a guess... It IS a total pain in the butt, but maybe if I explain my part of the network, it will help.

The network I work within consists of about 15 or so "host" computers and about 20 others that support it. Via our VSAT intranet, up to 8000 different remote sites can log into our hosts (up to 1000 or so at a time). These remote sites log in with these proprietary boxes that aren't really PC's or workstations. Each of these boxes has all of the IP's of my host computers programmed in. If one of the host IP's has to be changed, or if we add a host, it can take a week or so to proprograte the new IP info to all the sites (90% of them will be done in a matter of hours by a forced download, but if someone has their box unplugged, it can take us a long time to track someone down to take care of it.) I'm guessing that their is some hardware limit or something that doesn't allow these remoted boxes to simply do a NMS lookup... I'm not sure.
