 * I have been tasked with transferring a WordPress website from a test server (
   Linux server) to the client’s own server (Windows 2012 server).
 * So far so good as I have transferred the files and created the new database to
   go with it. Also updated the wp-config.php file to include the new database info.
 * As per documentation I have read elsewhere, I changed the DB_HOST in the config
   file from ‘localhost’ to the IP address of the new server.
 * When I try to load the website I get the following error:
 * **Notice: Use of undefined constant DB_HOST – assumed ‘DB_HOST’ in D:\inetpub\
   wwwroot\website\wp-includes\load.php on line 350 **
 * Warning: mysql_connect(): php_network_getaddresses: getaddrinfo failed: No such
   host is known. in D:\inetpub\wwwroot\website\wp-includes\wp-db.php on line 1482
 * Warning: mysql_connect(): [2002] php_network_getaddresses: getaddrinfo failed:
   No such host is known. (trying to connect via tcp://DB_HOST:3306) in D:\inetpub\
   wwwroot\website\wp-includes\wp-db.php on line 1482
 * Warning: mysql_connect(): php_network_getaddresses: getaddrinfo failed: No such
   host is known. in D:\inetpub\wwwroot\website\wp-includes\wp-db.php on line 1482
 * I can’t make sense of it! Can anyone help?
 * Thanks in advance!

 * I should mention that phpmyAdmin and mySQL are installed and apparently correctly
   set up on the Windows Server.
