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:inrequire’
from script/console:2:in `’
and is similar to ruby script\server too

Thanks,
Sawan.
