The default lease time is 24h for my known clients:

BTW, I use ISC DHCP3 server 3.0.14-13 binary for Debian Etch.

If I give
# cat /var/log/syslog | grep DHCPRELEASE | wc -l
the result is 0.

I guess this means that my clients (a mix of Windows 2k SP4 and XP Pro 
SP2) don't issue the release of the lease. Is it normal?

Clients are regularly powered off at the end of the day.
