Rails - Aug 2006 - gem install rails - problem - windows 2003 - Intranet

I have a windows 2003 in an intranet and I''m installing RoR on it, but 
when I try to install the rails with the command "gem install rails" I
got an error like :

 " ERROR: While executing gem .. (Errno::EBADF) Bad file descriptor - 
connect(2)"

Does any have any idea about how to fix it?

Thanks so much
