create DNS A-Records for these subdomainss at your dns registrar.[/QUOTE]
Thanks a lot for all your help Till, it's working fine now...
One more question on ISPConfig, how can I create a master FTP Account on PureFTPd that I can access the main web root folder, for example /var/www and access all website's folders?? Because when you create a ftp account on ISPConfig it goes for that specific domain only right?
