I just actually had two machines I just finished
looking at that were also having dhcp issues just now. Both a
Dell and a printer had failed to get dhcp addresses and had
defaulted to their built in auto-ip addresses. (Both of these
were machines that would have gotten 35.15 addresses because
they weren't currently registered.) I just kinda wrote it off
as a fluke, but maybe there's something more widespread going
on? Yesterday I had a machine that I registered, got it's 35.10
ip address, then shortly after I got a call saying that it
wasn't working again, and sure enough, it had a 35.15 address
once more, but when I went into the registration stuff, it was
recognized as having been registered (that machine I had to
unregister and reregister to get working again).
