ruby script/console error

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
