title: How do I connect Excel securely to sql server 2008?
body: <p>My company wants to have approximately 100 of their sales people (distributed around the country) to be able to run stored procedures from excel and return the data onto the spreadsheet. </p>
  
  <p>We have sql server 2008. i need to figure out a safe way to do this. </p>
  
  <p>i will create a form in excel where the user can push a command button to refresh the data based on the parameters that they choose. </p>
  
  <ol>
  <li>how can i ensure that the connection from excel to the sql server is secure?</li>
  <li>how do i run a stored procedure from excel?</li>
  </ol>
  
  <p>i found this to be very good information: <a href="http://office.microsoft.com/en-us/excel-help/connect-to-import-sql-server-data-HA010217956.aspx" rel="nofollow">http://office.microsoft.com/en-us/excel-help/connect-to-import-sql-server-data-HA010217956.aspx</a></p>

    <p>Windows Authentication    Select this option to use the Windows user
    name and password of the current user. This is the most secure method,
    but it can affect performance when many users are connected to the
    server.</p>
  </blockquote>
  
  <p>however, i would like your input on this. </p>
  
  <p>yes, the sales reps do have windows logins, but can i use this solution if they will actually be entering specifying the data criteria, then sending the criteria over into the stored procedure and then getting the data from the server?</p>
