Kyocera stealing IP addresses
In our enterprise we have about 300 computers and about 20 Kyocera printers. We use DHCP on W2K. We have disabled BOOTP. Intermittently these printers take an IP address from our HP printers. Any ideas what we should check for to stop this disruption?
Thank you.
Thank you.

This is not limited to printers. Use this process or all known network devices.
Hardcoding the the address at the device will not create a conflict, DHCP will simply not assig taht address unless a specific MAC request it. There is also a Description field so you can leave yourself a reminder of what is assigned.
Win2K DHCP server allows more flexibility than the more generic versions offered on simple nework devices and some pretty good tools to boot.

And just make a note to yourself to remove those records when you get rid of a older printer or other device, to prevent clutter and a large number of pre-assigned addresses which won't be used.

Sorry for the delay in getting back, I'm in a different time zone than most of you (Japan).
I'll go over to the shop and try to work on these great suggestions and get back to you in a few hours.

Thanks to all for your help.
I tried jonoakley's step by step instructions and so far, the intermittent problem has disappeared. craigmyster also suggested the same workaround (I think)
hdhondt might be closer to the truth but I wasn't able to do the research to isolate the problem.

craigmyster solution will result in a range of IPs being allocated as off limits to assignment by DHCP. If your printer IPs are within a range you can block that range and assign the Printer IP manually. The two solutions can be used in conjunction Block a range then assign address properties within the range to specific MACs through DHCP .
The main difference would be that you can set your printers to DHCP and be assured the the setting are the same as long as the DHCP server is available plus you are not limited to the set range.
It is a good habit to set aside ranges of IPs for certain devices such as Servers, SAN, Print Servers that way if you run into an IP incident you can tell by the IP where to direct your attention. It is all a matter of centralized control.

Or you can leave the IP hard coded and be done with it. The DHCP server will know that specific addresses belong to specific MACs and not assign them.
