title: SSRS Error after Changing User
body: <p>The "SQL Server Reporting Services (MSSQLSERVER)" was running as "NT Service\ReportServer".</p>
  
  <p>I changed the account to a domain account with local admin rights so it could have access to some LAN resources.</p>
  
  <p>Now I get "The report server cannot decrypt the symmetric key that is used to access sensitive or encrypted data in a report server database. You must either restore a backup key or delete all encrypted content."</p>
  
  <p>How do I restore the service as "NT Service\ReportServer" so that I can backup this key?</p>
