I've installed the dhcpd on my RH4.2 box as written in the documentation.
I instructed it, to give IPs from a range 192.168.2.3 to 192.168.2.250.
Next I booted WinNT on my other box, told them to use DHCP and rebooted
them. When the NT booted up, it got the IP 192.168.2.3, and everything
worked just ok.
But after that, I wanted to try dhcp out an changed the dhcpd.conf file. I
wrote that dhcpd should give the IPs in from the range
192.168.2.30-192.168.2.250. Restarted dhcpd and also WinNT. And here the
problems begin. The NT box gets the old IP (.2.3). I also tried to give
the NT box a static IP, but it wouldn't help.
