Before Installing Microsoft TCP/IP

Important The values that you use for manually configuring TCP/IP and SNMP must be supplied by the network administrator.

Check with your network administrator to find out the following information before you install Microsoft TCP/IP on a Windows NT computer:

• Whether you can use Dynamic Host Configuration Protocol (DHCP) to configure TCP/IP. You can choose this option if a DHCP server is installed on your internetwork. You cannot choose this option if this computer will be a DHCP server. For information, see "Using Dynamic Host Configuration Protocol" later in this chapter.
• Whether this computer will be a DHCP server. This option is available only for Windows NT Server. For information, see Chapter 13, "Installing and Configuring DHCP Servers."
• Whether this computer will be a Windows Internet Name Service (WINS) server. This option is available only for Windows NT Server. For information, see Chapter 14, "Installing and Configuring WINS Servers."
• Whether this computer will be a WINS proxy agent. For information, see "Windows Internet Name Service and Broadcast Name Resolution" in Chapter 12, "Networking Concepts for TCP/IP."

If you cannot use DHCP for automatic configuration, you need to obtain the following values from the network administrator so you can configure TCP/IP manually:

• The IP address and subnet mask for each network adapter card installed on the computer. For information, see "IP Addressing" in Chapter 12, "Networking Concepts for TCP/IP."
• The IP address for the default local gateways (IP routers).
• Whether your computer will use Domain Name System (DNS) and, if so, the IP addresses and DNS domain name of the DNS servers on the internetwork. For information, see "Domain Name System Addressing" in Chapter 12 "Networking Concepts for TCP/IP."
• The IP addresses for WINS servers, if WINS servers are available on your network.

You need to know the following information before you install the Simple Network Management Protocol (SNMP) service on your computer, as described in "Configuring SNMP" later in this chapter:

• Community names in your network
• Trap destination for each community
• IP addresses or computer names for SNMP management hosts

Although the Windows NT SNMP management agent supports management consoles over both IPX and UDP protocols, SNMP must be installed in conjunction with the other TCP/IP services. Once SNMP is installed, no additional configuration is needed to manage over IPX. If IPX is installed, SNMP automatically runs with it.
