title: Protect central app.config
body: <p>I have an application which is executed when a user logs out. This is achieved via GPO. The application needs access to a database. </p>
  
  <p>My App.config contains the connection string. I tried to encrypt it using aspnet_regiis but I just read that this works only per machine. While it worked on mine flawless it of course crashed on other machines. </p>
  
  <p>I can not find another way on how to protect the connection string in this scenario. I have no setup so I can not execute aspnet_regiis on the local machine. How do you usually handle this problem? </p>
  
  <p>Could you deploy the key for encrypting the App.config via GPO? Where do I find that key?</p>
