dhcp3-server is making some strange things

[Eduardo <dutche@gmail.com>]

Hi folks, I´m running a dhcp3-server on my Debian Sarge and I put all
the windows (XP and 2000) users on my network to work via dhcp.

A few machines get too slow, but the other are normal.

The tests I made was, the server is Debian and the client is the
Windows Slow machine:

First: Set the ip static on client and nothing changed.

Second: I stopped the dhcp-server3 daemon and the client got fast again.

I thought that might be some service in Windows that is making this
mess, but I stopped all that I can in client and still is slow.

Then I ran ettercap on the server machine, but I got no answer of what
could be happening. I saw just some netbios packages in idle state.

My server is running Bind9, is the internet server (nat with
iptables), samba server and dhcp server.

All my network is stopped right now, and I must put this working
again...(they will make me work on saturday..grrr)

Does anybody can help me? please



My dhcpd.conf is:

# The ddns-updates-style parameter controls whether or not the server will
