Dnsmasq and bind

Hello!

I have allready installed and configured bind correctly as this how to:

http://www.freepbx.org/support/documentation/howtos/how-to-install-bind-so-that-sip-extensions-continue-to-work-when-intern

But I have realized dnsmasq is installed and running by default and I realized that I get an error during the boot on.

Do I have to stop the service?

Thanks
