title: Windows Azure Backup suddently failing jobs - Error 100023
body: <p>The last couple of days Azure Backup has been failing jobs with error <strong>100023</strong>.</p>
  
  <blockquote>
    <p>The encryption passphrase stored for this computer is not correctly configured. The encryption passphrase can be configured from the Windows Azure Backup Agent MMC snap-in. In the Action pane, click Properties and then click the Encryption
    settings tab. Type the passphrase used for encryption of backups in the space provided.  </p>
  </blockquote>
  
  <p>I haven't changed the encryption password or location lately, so this is a bit unexpected.</p>
  
  <p>At first I tought It may be an outage with Azure Backup itself but it's been a couple of days and still I'm getting the same issue.</p>
  
  <p>I have since accessed the Backup Vault panel on manage.windowsazure.com and allowed re-registration for the affected server. However during the re-registration process I'm getting the same error.</p>
  
  <p>Any ideas?</p>
