multisite with www and without

Hi, I have run into a bit of a problem. I did a website at http://www.desdowd.com and then installed a multisite network to create the english version using a sub-folder at http://www.desdowd.qc.ca/en

It seem my network got rid of the www if you look at the english version it dropped the www.

So this created 2 problem for me. In my config file when I use this line : define(‘DOMAIN_CURRENT_SITE’, ‘www.desdowd.qc.ca’);
All is working well except my link to Network Admin is not working. If I drop the www and use : define(‘DOMAIN_CURRENT_SITE’, ‘desdowd.qc.ca’); My network admin link is working but my main menu in the main site is not working anymore.

Also, when I login as a SuperAdmin, my site does not let me managed both languages as it should and I end up always having to login the french and the english seperatly.

Any way to uniformized all this so that I don’t have to remove the www in the config file everytime I want to install or update a plugins.

Thank you
