title: SharePoint 2016 some Timer Jobs run time n/a
body: <p>I'm helpless... Since couple of weeks looking for a solution.
  Some TimerJobs (system jobs and custom) in my migrated SharePoint farm won't be executed. Migrated from 2010, over 2013 to 2016.
  Last run time is: N/A or via powershell 01.01.0001 00:00:00</p>
  
  <p>I spend a lot of time to look for a solution, and already did the following:</p>
  
  <ul>
  <li>Restarted timer service</li>
  <li>Restarted all servers</li>
  <li>iis reset</li>
  <li>Cleared SharePoint configuration cache</li>
  <li>Tried "Start-SPAdminJob -verbose", but it fails (also when I do "net stop SPAdminV4 / net start SPAdminV4")</li>
  <li>Started SharePoint Configuration Wizard</li>
  <li>Redployed the wsp and reactivated (for a custom timer job)</li>
  <li>Checked service accounts</li>
  </ul>
  
  <p>I'm also wondering about that some of them have also no web application associated. Is this normal?

  <p>Is there someone with an idea?
  Thanks for any help.</p>
