Login failed for user NT Authority\System
<p>I have <strong>ASP.NET MVC</strong> app that connects to <strong>MSSQL</strong> database on <strong>Windows Server 2008 R2</strong>. The thing is that I see this error and can't solve the problem:</p>

<pre><code>Login failed for user NT Authority\System
</code></pre>

<ul>
<li>I have created login under SQL Server for NT Authority\System and gave sysadmin access to my database (+ selected default database)</li>
<li>Application pool uses LocalSystem user</li>
<li>Firewall is turned off</li>
</ul>

<p>What may be a reason of my problem?</p>
