Cannot open database requested by the login. Login failed for user 'NT AUTHORITY\SYSTEM'. Quartz Scheduler Windows Services
<p>Have my service set to login using 'Local System Account' with 'Allow service to interact with desktop' ticked.</p>

<p>Here's my C# connection string which works allowing interaction with DB when I execute the application outside of the Quartz/Windows Service:</p>

<pre><code>  &lt;connectionStrings&gt;
  &lt;add name="ArbDBConnStr"
      connectionString="Data Source=(LocalDB)\MSSQLLocalDB;Initial Catalog=aspnet-Arb-20160906102730;Integrated Security=True"
      providerName="System.Data.SqlClient" /&gt;
  &lt;/connectionStrings&gt;
</code></pre>

<p>What do I have to do to enable the the windows service to be able to access the db?</p>

<p>Also no info in SQL Server logs that I can see that would shed any light - what should I be seeing?</p>
