DHCP static leases

[Denis Laventure]

I think the same thing.

 

We had this problem here too. Use Wireshark on the same subnet to find the IP of the workstation that's sending those wrong ack. We had 2 of those infected machine on our network. I don't remember if we found the virus, but I think we just formatted the PC.

	Hi Brandon,
	
	                        Does your dhcp server range includes the static lease ?

	Hello everyone.
	
	I have had a strange problem for some time with dhcpd.
	I have quite a bit of static leases defined in the configuration file, but

	address and the dhcp server will acknowledge that request.  This creates
	an IP conflict when the machine with the static lease turns on.  Is there a
	configuration option to fix this?  Thank you
