Ruby on Windows send email using SMTP library - ruby

Question

I have the following code that works perfectly on a Mac but fails on windows.
require 'net/smtp'
opts = {}
opts[:server] ||= 'mycompany.com'
opts[:from] ||= 'user0#mycompany.com'
opts[:from_alias] ||= 'Example'
opts[:subject] ||= "You need to see this"
opts[:body] ||= "Important stuff!"
msg = <<END_OF_MESSAGE
From: #{opts[:from_alias]} <#{opts[:from]}>
To: <user0#mycompany.com>
Subject: #{opts[:subject]}
#{opts[:body]}
END_OF_MESSAGE
Net::SMTP.start(opts[:server]) do |smtp|
smtp.send_message msg, opts[:from], "user0#mycompany.com"
end
With the following error message...
Z:\util>ruby test.rb
C:/Ruby200/lib/ruby/2.0.0/net/smtp.rb:540:in `initialize': Permission denied - c

from C:/Ruby200/lib/ruby/2.0.0/net/smtp.rb:456:in `start'
from test.rb:19:in `<main>'
Is there something missing that i need on the windows environment to send the email?
Thanks
