title: Can't connect to SQL Server using odbcDriverconnect (RODBC)
body: <p>I have previously made a connection multiple times using RODBC's OdbcDriverconnect():</p>
  
  <pre><code>con    &lt;- odbcDriverConnect(paste0("driver={SQL Server};server=", srnm,";trusted_connection=true"))
  </code></pre>
  
  <p>Recently I keep getting the following error and I have no idea how to fix this:</p>
  
  <pre><code>Warning messages:
  1: In odbcDriverConnect(paste0("driver={SQL Server};server=", srnm,  :
    [RODBC] ERROR: state 08001, code 18, message [Microsoft][ODBC SQL Server Driver][Shared Memory]SSL Security error
  2: In odbcDriverConnect(paste0("driver={SQL Server};server=", srnm,  :
    [RODBC] ERROR: state 01000, code 1, message [Microsoft][ODBC SQL Server Driver][Shared Memory]ConnectionOpen (SECCreateCredentials()).
  3: In odbcDriverConnect(paste0("driver={SQL Server};server=", srnm,  :
    ODBC connection failed
  </code></pre>
  
  <p>Thanks in advance.</p>
