Howto reach my site internally

Could someone help me (newbee) to be able to see my site from another PC on my network ?
The site is in the default folder (vhosts)

Thanks in advance.

* setup domainname for your site in ehcp, in your server,
* move your files into vhosts/yourftpuser/domain.com/httpdocs
* in your local desktop, edit hosts file, put "192.168.1.100 www.yourdomain.com" for ex, if your server's internal ip is 192.168.1.100
this way, you will be able to see your domain internally.
