Internet Service Provider

In this scenario, an Internet service provider uses Windows NT Server to set up an information service network. The network provides an Internet connection and other network services, including a mail server, fax server, database hosting, software distribution, and other custom applications.

Figure 6.2 Internet service provider with Internet access and network services

The computer running Windows NT Server is on the Internet service provider's network, which also has a leased line to the Internet. The Remote Access Service accepts calls from customers who want Internet access or network services. RAS routes traffic to and from remote customers to servers on the private network and to and from the Internet.

For this scenario, you need to install and configure the following hardware or services:

• A computer running the Remote Access Service
• TCP/IP networking protocol on all computers that will use the Internet
• A multiport adapter, which allows multiple remote clients to dial in to the computer running RAS
• Network interface cards on all servers
• Internet browsers, such as Internet Explorer, on all remote clients that will access the Internet
• Dial-Up Networking on remote clients that will dial in to the RAS server
• Internetwide domain name resolution, as described in the section, "Establishing an Internet Connection," in Chapter 2, "Connecting Windows NT Server to the Internet."
