Enter the complete name of the local host in the Fully-qualified Local Host Name text box. The fully-qualified local host name typically takes the form of the local host name plus the domain name server (for example, bigbox.net.srv.com).
Enter a short host name in the Short Local Host Name text box. The short local host name is the abbreviated, more common method of referring to the host, usually only a single word.
When you have entered the appropriate information, click Next to continue.
