title: Can't create dbo schema
body: <p>I have been searching a lot for a solution for my problem but haven't find
  any.</p>
  
  <p>The problem is when I create schema dbo I get below error.  </p>
  
  <pre><code>CREATE SCHEMA dbo;
  Msg 2760, Level 16, State 1, Line 2
  The specified schema name "dbo" either does not exist or you do not have permission to use it.
  Msg 2759, Level 16, State 0, Line 2
  CREATE SCHEMA failed due to previous errors.
  </code></pre>
  
  <p>Some explanation I use a product called DbWrench for database design and when
  the design is ready a generate the script which create all the objects that are missing in the MSSQL database that I'm connected to.
  So the problem as I mentioned is the above  statement CREATE SCHEMA dbo;</p>
  
  <p>In the generated script is the first statement CREATE SCHEMA dbo;</p>
  
  <p>So even if I log in as administrator and run this statement CREATE SCHEMA dbo; 
  from within SQL Server I get the same error.</p>
  
  <p>Here is just the first rows in the script that will be run agains the connected
  MSSQL Server</p>
  
  <pre><code>USE DiseMSSQL_new;
  
  CREATE SCHEMA dbo;
  </code></pre>
