ruby script/console error

Hi, I am a newbie in ROR I have an application checked out from repository on a windows machine and have all the required gems installed. I can have the rake commands work with the project but any other. I was trying to run the command from the cmd window C:\sawan\path\to\projectapp>ruby script/console

I get the following error <internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- script/../config/boot (LoadError)         from <internal:lib/rubygems/custom_require>:29:in `require'         from script/console:2:in `<main>' and is similar to ruby script\server too

Thanks, Sawan.
