I'm using this tutorial to try install apache - and then install php and mysql: http://expertester.wordpress.com/2009/02/17/apache-php-mysql-on-vista-x64/ I want a configuration only to view the sites I'm building. I did the same as write in the tutorial, but when i write bin\httpd.exe -k install on msdos i received this message: " Testing httpd.conf... Errors reported here must be corrected before the service can be started. httpd.exe:Could not reliably determine the server's fully qualified domainname, using xxx.xxx.x.xxx for Server Name " ---------- but the servername is localhost. Note: my OS is Windows Vista Premium 64 bits How can i solve this?
