<p>My scheduled reports in SQL server won't run. I checked the logs and found the job that was failing. The error message in the log was:</p>

<blockquote>
  <p>'EXECUTE AS LOGIN' failed for the requested login 'NT AUTHORITY\NETWORK 
  SERVICE'. The step failed. </p>
</blockquote>

<p>I'm using SQL authentication for the report so it shouldn't be issues with the permissions to the data. No sheduled reports on the server will run.</p>
