Getting copy of rails site running

Im a noob to Ruby/Rails(current .Net developer) but have recently been
assigned the tasks of making changes to a existing site that is deployed
on linux. Im trying to get the site running in Windows to i can do the
development but hitting a wall.

I think i have installed all the Gems but every time I run ruby
Script/Server I get this error below. Any Ideas?

C:\rails\rails_apps\zchamp_src>ruby script/server
internal:lib/rubygems/custom_require:29:in require': no such file to load -- script/../ config/boot (LoadError) from <internal:lib/rubygems/custom_require>:29:inrequire’
from script/server:2:in `’

rails 2.3.5

Thank you,

Daniel
