DHCPINFORM / DHCPACK appearing every few hours in syslog

Hello,

hcpd: isc-dhcpd-V3.0.1
clients: Windows XP Pro

I have the default lease time set to 7 days. However, I'm seeing DHCPINFORM messages for each client every few hours. I would only expect to see one after 3.5 days.

Does anyone know why this is?

Thanks,
Steve :)

...yes - I agree, but you have XP systems on the network. If you are not running a WINS server, the XP systems will negotiate amongst themselves and run an distributed WINS capability anyway. This a a 'feature' of XP:)

This is because the WINS current database maintenance is done using DHCPInform and DHCPACK Packets.

Hence the requirement for much more regular appearances of these packets:

Thanks for the answer pjedmond, but I'm not running a WINS server, just Samba (WINS disabled).

Damn those pesky features!

So, assuming I have no DHCP problems that I want to know about, the only way to stop this is to prevent syslog from logging them?
