title: (rsErrorOpeningConnection) Could not obtain information about Windows NT group/user
body: <p>I am trying to deploy a report to the Reporting Services Server but keep running up against this error:</p>
  
  <blockquote>
    <p>An error occurred during client
    rendering. An error has occurred
    during report processing.
    (rsProcessingAborted) Cannot create a
    connection to data source
    'dataSource1'.
    (rsErrorOpeningConnection) Could not
    obtain information about Windows NT
    group/user 'DOMAIN\useradmin', error
    code 0x5.</p>
  </blockquote>
  
  <p>Here’s my situation: Everything is being ran using DOMAIN\useradmin and the report is using a remote database.</p>
  
  <p>Reporting Services and SQL Server are both ran under DOMAIN\useradmin.  DOMAIN\useradmin is a windows AD login and is part of the server machine Administrators group.</p>
  
  <p>My test report is using a data source model that in turn is using a data source that is connection to a database on a different SQL Server.  The data source is using <strong>“Credentials stored securely in the report server”</strong> with the options <strong>“Use as Windows credentials when connecting to the data source”</strong> and <strong>“Impersonate the authenticated user after a connection has been made to the data source.”</strong></p>
  
  <p>I am using the credentials of DOMAIN\useradmin that is the db owner of the remote database.</p>
  
  <p>DOMAIN\useradmin is assigned the roles, <strong>System Administrator, System User and Browser, Content Manager, My Reports, Publisher, Report Builder.</strong></p>
  
  <p>So if everything is being run under an über AD account, why I am getting this Could not obtain information about Windows NT group/user 'DOMAIN\useradmin' error?</p>
  
  <p>Under normal circumstances , an AD login with Publisher permissions will developing reports using a datasource model created by DOMAIN\useradmin but using one of the remote database’s users which is mapped from yet another AD login. </p>
  
  <p>I ran the following statements and non errors were returned:</p>
  
  <pre><code>use master
  go
  
  xp_grantlogin 'DOMAIN\useradmin' 
  go
  
  xp_logininfo 'DOMAIN\useradmin' 
  go
  </code></pre>
