The BAD_ADDRESS

What type of DHCP server?  Windows Server, router, firewall, Cisco box ... and what is the complete, specific error message?

BAD_ADDRESS typically means that the DHCP server attempted to lease that address to a client but determined that something on the network is already using the address. It creates a BAD_ADDRESS record so that it won't keep attempting to assign an address that's already in use.

I have a windows server 2016 dhcp server .

it just runs out of leases.

ESther

If you look at the active leases in the DHCP console, is it completely full of BAD_ADDRESS entries?

no ther are probably like 300 or so.

This may be caused by a malfunctioning device on the network. Do the BAD_ADDRESS entries have legitimate MAC addresses associated with them? If not, check the DHCP logs (at C:\Windows\System32\dhcp), which should show the actual MAC addresses. If all of the applicable log entries show a single MAC address, see if you can determine what device it belongs to. This MAC Address Lookup site may help, as it should at least be able to identify the manufacturer.

I see allot of these.

Sorry for the delay. Are you saying that you're seeing a lot of log entries referencing that particular device (DELLOPTRM09A.lesd.us), or just a lot of those events referencing different devices on your network?

Also, have you checked to see whether you've got another DHCP server handing out addresses on the same network?

No, not that particular device just allot or dns update failed ones.

In that case, I don't think those "DNS update failed" log entries are related to the BAD_ADDRESS records in the DHCP database.
