Can't execute queries on SQL Server
<p>For some reason queries that have worked in Management Studio in the past no longer function. A query such as <code>SELECT * FROM Users</code> no longer works, but will work if I type the following:</p>

<pre><code>SELECT * 
FROM [SmartTapp].[dbo].[users]
</code></pre>

<p>The error message I get is:</p>

<blockquote>
  <p>Msg 208, Level 16, State 1, Line 1<br>
  Invalid object name 'users'.</p>
</blockquote>

<p>This occurs for all tables.</p>

<p>I'm not seeing anything SQL related in the Event Viewer.  I haven't done anything to the server that I'm aware of.</p>
