i have developed a web application using ASP.NET and i am going to upload it to my company server(not in a
web hosting provider web space).so i want only the domain name from the provider like - www.somename.com
i use windows authentication to avoid internet uses from viewing the company intranet site.
i have two problems

1.how to make my company staff access the intranet application by typing www.somename.com.
  because i have not uploaded it to a web hosting space only uploaded it to the company server
2.i also want to know that is it safe to use windows authentication to prevent internet uses
  from accessing the company intranet application.

1. Set up your internal DNS on your PDC to point all request to the domain name to your internal web server.

2.Put the intranet application on a web server that does not face the internet.

Alternately, you can put an A record in your internal network's DNS server and use any name to point to the internal IP address of your Intranet site.

If you don't have an internal DNS server, you can put an entry in each local computer's Host file.
