problem with dhclient

[c4nt1]

in other os's (debian, slackware) I can just use dhclient eth0 (ethernet) or eth1 (wlan) and the dhcp client handles the rest from there. But now, whenever I try dhclient I get an error message that says

Sending on LPF/eth1/00:0e:35:2c:75:85
Cant bind to dhcp address: Address is already in use
Please make sure that there is no other dhcp server
running and that theres no entry for dhcp or
bootp in /etc/inetd.conf. Also make sure you
are not running HP JetAdmin software, which includes
a bootp server.

How to detect a running dhcp server, kill it, or restart it or whatever would be helpful info, or any possible way to fix this problem. For some reason it doesnt work on either eth0 or eth1, although I am connected to the internet through eth0. Thanks!
