Kazaa without MS-CLIENT

Hi,

I love to download MP3 music. I have DSL connection @ office through LAN. Recently my NETWORK ADMINISTRATOR has uninstalled the MS-CLIENT from Server, so now I can?t run Kazaa on my PC (means it does not connects).
Please note I am using Windows XP, while Win 2000 is on the Server.

My question is how can I run Kazaa without MS-CLIENT on my computer?

Thanks
Bilal
