A Web server named Web1 hosts an internal Web site named WebSite1. Users connect to WebSite1 from the Internet by using the URL http://website1.wingtiptoys.com. The domain name website1.wingtiptoys.com is resolved by using the Hosts file that is located on each client computer.
Users frequently work from home. Home users connect to the internal network by using SSTP-based VPN connections.
