The Internet Software Consortium DHCP distribution includes a DHCP client, a DHCP server, and a DHCP relay agent. DHCP is a protocol for automatically configuring nodes on an IP network. The ISC DHCP server and client are well known for being extremely configurable, reasonably easy to use, and quite efficient.
Anticipating the next move
If Microsoft's strategy is to come out with a cheap web server that provides proprietary features so as to lock out Apache and Netscape, the right solution is to provide a free, open solution to the exact same people. In other words, a version of Apache on Win98 that's just as easy to use as whatever Microsoft will be shipping. I realize this sounds like promoting Win98, but it's not actually that. What it actually is is promoting open source software and confusing the market so Microsoft can't take it over, and so that incompatible features Microsoft provides will be seen as non-competitive, and will not work to Microsoft's advantage.
Version 2.0 is out!
I mention this because a previous comment says it's coming soon, but in fact it's here! :')
