How to run Google Chrome with Selenium RC?

I am trying to test my site with Selenium RC + Nunit + asp.net.

I can get my tests to work in Firefox,Safari,opera,IE 8 but not google chrome. I put this in for the browser arugment

 selenium = new DefaultSelenium(Server, ServerPort,
                                          "*chrome", DomainURL);

This always loads up Firefox though and not good chrome.
