title: Failed to encrypt the section 'connectionStrings' using provider 'RsaProtectedConfigurationProvider
body: <p>Failed to encrypt the section 'connectionStrings' using provider 'RsaProtectedCo
  nfigurationProvider'. Error message from the provider: Object already exists.</p>
  
  <p>I followed the guide in <a href="http://msdn.microsoft.com/en-us/library/2w117ede.aspx">http://msdn.microsoft.com/en-us/library/2w117ede.aspx</a> but in step 3 in To grant the ASP.NET identity access to the RSA key container, it says that my identity is my workgroup\username, I do not have impersonation in my web.config file though</p>
  
  <p>I am encrypting web.config using my machine using asp_regiis, then using visual studio to debug then it came with this error</p>
