title: Unable To Open SQL Cnnnection With Windows Authentication - New SQL Server Install - Error Number: 18456 Severity: 14 State: 1 Line Number: 65536
body: <p>I recently received a new work laptop and had to have IT install SQL Server 2014 on it. Initially when they configured the machine I was not set as an admin on it, they made the change after they mailed it to me. When in SMSS I try to log in and get this error:</p>
  
  <blockquote>
    <p>Cannot connect to HENA009617-W541.</p>
    
    <p>Login failed for user 'My domain user name'. (.Net SqlClient Data Provider)</p>
    
    <p>Server Name: HENA009617-W541<br>
    Error Number: 18456<br>
    Severity: 14<br>
    State: 1<br>
    Line Number: 65536</p>
  </blockquote>
  
  <p>Does anyone have any recommendations on correcting this or would I have to have SQL Server reinstalled?</p>
  
  <p>Thanks</p>
