The two problem machines have names like "Eli's Computer" or "Diane's G4 MDD" or some such. They've been set for years, because I use file sharing every so often. Hmmm. I can't remember, but I wonder if the apostrophes are in the names.

It looks like it should remove everything that isn't currently connected -- and maybe remove and reassign everything that is. > >I tried entering the machine names into the optional DHCP name box > >(forgot exactly what it's called) in the System Prefs/Networking/ > >Ethernet/DHCP window, but that had no effect, other than, when I > >clicked "Apply Now" it caused the computer to release its current IP > >and obtain a new one. > > The DHCP name box is simply a keyword used to get a specific > assignment from the DHCP server.

That way the name works properly with dns too. Thank you for the helpful information Dan. I will experiment tonight. I think I will first try shutting down the machines in question. Then remove their entries from the DHCP table. Then boot the machines back up. If that doesn't work, I'll try changing their names to something with no apostrophes. If that fails, then I'll change it to no spaces. I think that's a systematic test which should reveal the ultimate cause -- unless it fails to resolve the issue. :-) I also need to clean the gutters tonight, so if I'm too tired afterward for computer fun, it could be another day or two before I experiment... Completely off topic, I've found that tying a Mosquito Dunk <http:// amzn.com/B0002568YA> to the little cross bar in the gutter with a bit of kevlar string really seems to cut down on the mosquito population. One dunk for each independent section of gutter.
