title: Gem Install Connection Issues in Hyper-V
body: <p>I have a Windows Server 2010 VM running via Hyper-V.  I can connect to individual gems with a web browser from within the VM, however when I run gem install for any gem, the connection times out with the error I've pasted below.  The image is using a virtual switch - do you think this is causing the problem?  I'm not sure how to troubleshoot this.  </p>
  
  <pre><code>C:\Ruby193\bin&gt;gem install rails -V
