The following describes how to configure Small Business Server (SBS) 2000 in a scenario where the server uses a modem or terminal device such as an Integrated Services Digital Network (ISDN) device to connect to the Internet. This article may help you resolve some of the following issues:

• You experience slow start times during "Configuring Network Connections."
• You are unable to access the Internet.
• Users are unable to log on to the domain. First, ensure there is no messgae concerning the establishment of trust
• Exchange Server cannot send or receive e-mail messages.
• Event ID 5775 DNS deregistration errors are logged.

If a server uses a modem or terminal device to connect to the Internet, the DNS server is the pivotal point for Active Directory and Local Area Network (LAN) connectivity. Active Directory client computers (including the server and its services) use DNS to locate domain controllers for administration and logon procedures. For Active Directory clients and servers to function correctly, you must have a DNS server installed and configured with the appropriate DNS zone information.

If only one adapter is used to connect to the Internet, through a router for example, there is a different procedure. There is a further procedure for servers using two adapters.

A dial-up connection is established using Dial-up Networking or Remote Access Services (RAS). The hardware used for a dial-up connection is typically an analog modem or an ISDN terminal adapter. These devices must be configured through the Modems page of Control Panel. They may be connected to Small Business Server through a serial port or a multiport serial board, or they may be internal.

Dial-up Configuration. A server running Small Business Server is connected to the LAN through a network adapter and to the ISP through a modem/terminal adapter. This dial-up device could be an internal card or an external device connected through a serial port or serial board.

The Internet Connection Wizard in SBS is designed to help you configure Windows 2000 networking through LAN connections or remote dial-up connections, Exchange 2000 Server, and Internet Security and Acceleration (ISA) Server 2000.

In an ISA environment it is also worth reviewing how to configure SBS/BackOffice 2000 and Exchange Server with ISA

For a modem connection, or any dial-up connection that uses a phonebook entry to dial, you will need the following information from your Internet service provider (ISP):

• The account name (or UserID required to dial into your ISP)
• The password for the account
• The type of e-mail used: Microsoft Exchange Server (which uses SMTP, or Simple Mail Transfer Protocol) or POP3
  • For Exchange Server (SMTP) e-mail, you will also need the host name or IP address of the ISP's SMTP server. If your ISP queues mail for Small Business Server to pick up when it dials in, you will need to know the appropriate signaling, or "de-queuing" command.
  • For POP3 mail, you will need the host name or IP address of the POP3 and SMTP server at your ISP.
• Your Internet domain name

1. Verify DNS settings for the Local Area Connection for the internal network adapter.
2. Set the binding order.
3. Run the Internet Connection Wizard.

1. Click Start, point to Settings, and then click Network and Dial-up Connections.
2. Right-click Local Area Connection, and then click Properties.
3. Right-click Internet Protocol (TCP/IP), and then click Properties.
4. Confirm that the installation uses the following Internet protocol (IP) address settings (these settings are the default settings for a new installation of SBS 2000):

   IP Address: 192.168.16.2
   Subnet Mask: 255.255.255.0
   Default Gateway:

5. Confirm the following settings in Internet Protocol (TCP/IP) properties:

   Preferred DNS server: 192.168.16.2
   Alternate DNS server: blank

   NOTE: The preferred DNS server uses the IP address of the network adapter.
6. Click Advanced, and then click the WINS tab.
7. Verify that your server's internal IP address is listed in the WINS addresses list. If it is not listed, click Add, and then add your server's internal IP address.
8. Click OK, and then click OK.

1. In Control Panel, double-click Network and Dial-up Connections.
2. On the Advanced menu, click Advanced Settings.
3. Click Local Area Connection in the Connections box, and then click the arrow buttons to arrange the connections so that Local Area Connection (for your internal network adapter) precedes (Remote Access connections).
4. Click OK.
5. Quit Network and Dial-up Connections.
6. If you receive a message that asks if you want to restart the server, click Yes.

Before starting, you may wish to inspect the flow-chart associated with the ICW procedure.

1. Click Start, and then click Small Business Server Administrator Console.

   The Small Business Server Internet Connection Wizard (ICW) can be started from the Small Business Server Console in a couple of ways.

   • ICW can be called from the To Do List or from Manage Internet Access under More Tasks.
   • If Internet connectivity changes need to be made after the wizard has been run, select Configure Internet Hardware from the Manage Internet Access page of the Small Business Server Console, and then make any changes necessary.
   • Click Start, click Run, type icw, and then click OK.
   
   The Welcome to the Small Business Server Internet Connection Wizard page.
2. This first page is a simple introduction. Click Next.
3. Select an ISP for a new Internet account is used to connect to a Microsoft Referral Server that helps locate ISPs in your area that have special offerings for customers of BackOffice Small Business Server.

   In some cases these ISPs provide an online sign-up that configures the appropriate Small Business Server services. By selecting Select an ISP for a new Internet account, you launch the Internet Connection Wizard. The ICW then dials the Microsoft Referral Server and downloads a list of ISPs that have special offerings for Small Business Server customers. Therefore, in order to take advantage of this feature, you must have a functional modem on your server.

   If it supports online sign-up, once your new ISP has received your user, system, and billing information, the sign-up server generates an .ins file that is downloaded to your server. This .ins file will configure your dial-up networking connection, Proxy Server, Microsoft Exchange Server, and the information required by the Web Publishing Wizard. Some ISPs distribute sign-up floppy disks. If your ISP does this and is configured specifically for Small Business Server, you will not need to use the Small Business Server Internet Connection Wizard. Follow the instructions included with the sign-up disk to continue the installation.

   
   The Set Up Connection to Your ISP page.
4. If you choose Connect to the Internet from the Set Up Connection to Your ISP page (figure above, you are presented with the Configure Hardware page. Through this page you tell Small Business Server what Internet communications hardware connects the server to your ISP.
   The type of hardware determines what other information you'll need later in the wizard; clicking the Form button for each option displays the information you'll need if you select that option.

   Select Modem or terminal adapter whenever the hardware on the server is detected by the Windows NT operating system as a modem and can be accessed through dial-up networking and the Remote Access Service. This includes analog modems and ISDN terminal adapters.
   Before beginning with the Internet Connection Wizard, these devices should be installed through the Modems area of Control Panel and be configured as ports through the Remote Access Service with dial-out access.

   
   The Configure Hardware Page
   On the Configure Hardware page, click Modem or Terminal Adapter, and then click Next.
5. When Modem or terminal adapter is selected on the Configure Hardware page, you will be presented with the Set Up Modem Connection to ISP page.
   If a phonebook entry has been previously created to connect to the ISP, you can select that entry. You will need to enter the credentials (account name and password) so that Proxy Server and the Exchange Server Internet Mail Service can connect when automatically dialing the ISP. In Internet Service Manager, these credentials are configured on the Credentials tab for Proxy Autodial for the Web Proxy or WinSock Proxy properties. These credentials are also set in Microsoft Exchange Administrator, under the Dial-up Connections tab of the Internet Mail Service.
   Clicking the New button will launch the Dial-up Networking New Phonebook Entry Wizard to assist in the creation of a new phonebook entry.
   
   The Set Up Modem Connection to ISP Page
   Click the dial-up entry for your Internet service provider (ISP) connection or click New to create a new one. To create a new connection:
   1. In the ISP account name box, type the user account provided by the ISP.
   2. Type the password to be used to log on to the ISP in the Password and Confirm Password boxes.
   3. If the ISP provides you with static IP addresses for your dial-up connection, click to select the I have a static IP address from my ISP with this connection, and then type the IP address information provided by the ISP.
   4. Click Next to continue the wizard.
   NOTE: To find out more about information that is requested by or required in the wizard, click More Information in the wizard.
6. Configure network adapters.
   NOTE: If more than one network adapter is present, configure the adapter that has the 192.168.16.2 IP address.
7. On the Configure Internet Mail Settings page, click Use SMTP for Internet mail in the Exchange Server box, type the appropriate Post Office Protocol 3 (POP3) setting for your environment or configuration, and then click Next.

   Client systems use the POP3 protocol to retrieve e-mail stored on a server. In the Small Business Server environment, Proxy Server manages the connection to the ISP, preventing outsiders from reaching the LAN and optionally preventing LAN users from reaching the Internet.
   When you create user accounts for Small Business Server, you also configure the users' computers. If your users need access to POP3 e-mail accounts on the ISP's e-mail server, you need to configure their machines accordingly. Give those users' computers the WinSock Proxy client software so they can reach the Proxy Server, and add Internet Mail manually to each of those users' profiles in the Microsoft Outlook(r) messaging and collaboration client.

   
   The Send and Receive POP3 Mail Page

   NOTE: If you want to configure POP3 in the Internet Connection Wizard, click More Information in the Internet Connection Wizard to refer to the additional help provided by the wizard.

8. Once the networking pieces have been configured, the next step establish the e-mail configurations.

   The Configure Internet Mail Settings page configures Small Business Server to use Internet e-mail. If you are using SMTP e-mail through Exchange Server, select the Use Exchange Server for Internet mail option, which activates the Microsoft Exchange Internet Mail Service in Small Business Server. This is the option to choose, whether you host your own Internet domain and SMTP mail through a full-time connection or you dial in to an ISP that queues your mail until you connect.
   Selecting Disable Exchange Server Internet Mail will disable the Microsoft Exchange Server Internet Mail Service. This option disables only Internet mail through Exchange Server; it does not affect the ability to send mail to others on the local Small Business Server-based network. If you have already configured or customized your Exchange Server settings and do not wish to override these settings, select Do not change my Exchange Server settings.

   If you will be retrieving e-mail from POP3 mailboxes at your ISP instead of directly through SMTP, select the Use POP3 for Internet mail option.

   
   The Configure Internet Mail Settings Page
   On the Configure Internet Domain Name page, type the domain name where the user needs the messages to be delivered. For example, if the user receives messages as "userx@microsoft.com", type microsoft.com as the domain name.
9. Click Next.
10. On the Configure SMTP Server Address page, click Use domain name system (DNS) for mail delivery.

    If in the Configure Internet Mail Settings page you select the option Use Exchange Server for Internet mail, the wizard presents the Configure SMTP Mail Delivery page. This page will allow you to configure the sending properties of the Microsoft Exchange Internet Mail Service. The choices available to you depend on the connection typ, e: for a demand-dial router connection or a dial-up connection, select the Forward all mail to host option.

    If you do not have a full-time connection to the Internet, you should select Forward all mail to host, which covers dial-up connections, dial-on-demand routers, or any connection that does not maintain a full-time Internet connection. This option will set the Internet Mail Service to forward all messages to an SMTP relay host provided by your ISP. This relay host can be entered by its IP address or fully qualified domain name (for example, exchange1.isp.com or 192.168.16.1). If a dial-up connection is established through this wizard, the option to use DNS is unavailable.
    
    The Configure SMTP Mail Delivery Page

    NOTE: Some ISPs may require you to forward all outbound messages to one of their e-mail servers for delivery. In this case, click Forward all mail to hosts, type the IP address of the ISP relay server, and then click Next. A Domain Name needs to be configured as well.

11. On the Receive Exchange Mail page, click the appropriate option. Your selection depends on how you are going to retrieve messages from the ISP. For example, if you retrieve messages using the Microsoft Exchange Connector for POP3 Mailboxes, click Do not send a signal.
    The Receive Exchange Mail Page

    NOTE: You may need to enable message dequeuing for mail retrieval depending on the mail retrieval method that you use. It is recommended that you discuss this issue with your ISP to ensure compatibility.

    To prevent download failures due to improper POP3 configuration, configure your SBS server for DNS by performing the following steps. If you have a dial-up connection, use the following steps to configure DNS for your server:

    1. Click Start, click Dial-Up Networking, click Programs, click the Accessories folder, and then click Dial-Up Networking.
    2. Select the entry for the dial-up connection used by the POP3 connector. Then click the More button and click Edit entry and modem properties.
    3. When the Edit Phonebook Entry dialog box is displayed, click the Server tab, and then click TCP/IP Settings.
    4. Click Specify name server addresses.
    5. Enter your primary and secondary DNS server IP addresses in the dialog box. Leave the primary and secondary WINS address entries at their default entries (0.0.0.0), unless instructed otherwise by your ISP.

       Some IPs dynamically assign a DNS server entry to dial-up clients. Contact your ISP to determine the appropriate setting for your network.

       Click OK to close each dialog box.
    The settings are updated the next time the connection is dialled.

12. Click Next.
13. If the Mail Retrieval Frequency page is displayed, enter the time interval that you want your server to call the ISP for mail retrieval if a connection has not already been established. Fifteen minutes is the minimum value available.
14. Click Next.
15. Click Enable ISA server packet filtering option and any required packet filters.

    NOTE: The My Web Server and My Web-based Mail Server options are dimmed for a dial-up configuration.

16. Click Next.
17. If you receive a warning message about packet filters, click OK.
18. Click Finish.

To help with client connectivity, you may have to modify the DHCP scope for your local network. The following configuration is recommended for the DHCP scope; this configuration works in a majority of configurations. This example assumes that you are using the default setting that is provided with the SBS installation.

1. Click Start, point to Programs, point to Administrative Tools, and then click DHCP.
2. Click to expand the tree until the following data is displayed:

   server.domain.local[192.168.16.2]
