Requirements
Prior to configuring TCP/IP on a computer running Windows 2000, you need to know whether your network supports a dynamic TCP/IP configuration, which uses the Dynamic Host Configuration Protocol (DHCP), or whether your network requires a manual TCP/IP configuration. Some existing networks either do not use DHCP or require that TCP/IP configuration is performed manually for each computer.
If DHCP is not being used to configure TCP/IP dynamically, obtain the following information from your network administrator to configure TCP/IP manually:
- The IP address and subnet mask for each network adapter that is installed on the computer.
- The IP address for the default local gateway (IP router).
- The name of your DNS domain and the IP addresses of the DNS servers on the
network.
- The IP addresses for the WINS servers, if WINS services are available on your network.
This walk-through assumes you have already installed Windows 2000 on your LAN. If you have NOT installed Windows 2000 on your LAN yet, please refer to Dialup Networking with Windows 2000.
NOTE:
- You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure.
- TCP/IP is installed as the default network protocol if network adapter hardware was detected during Windows 2000 Setup. You only need to follow these
instructions if the TCP/IP default selection was overridden during Setup.
Go to Start | Settings | Network and Dial-up Connections:
Right-click the network connection for which you want to install and enable TCP/IP, and then click Properties. The following window should appear:
If Internet Protocol (TCP/IP) is not in the list of installed components, then do the following:
- Click Install.
- Click Protocol | Add.
- In the Select Network Protocol dialog box, click Internet Protocol (TCP/IP), and then click OK.
Verify that the Internet Protocol (TCP/IP) check box is selected, and then click OK.
Go to Start | Settings | Network and Dial-up Connections:
Right-click the network connection for which you want to install and enable TCP/IP, and then click Properties. The following window should appear:
Click Properties to display the following screen:
Click Obtain an IP address automatically, and then click OK.
NOTE: Windows 2000 uses Automatic Private IP Addressing (APIPA) to automate Internet Protocol (IP) configuration of network connections. By default, the computer first tries to contact a DHCP server on the network and dynamically obtain configuration for each installed network connection, as follows:
- If a DHCP server is reached and leased configuration is successful, TCP/IP configuration is completed.
- If a DHCP server is not reached or leased configuration fails, the computer uses APIPA to automatically configure TCP/IP. When APIPA is used, Windows 2000 determines an address in the Microsoft-reserved IP addressing range from 169.254.0.1 through 169.254.255.254. This address is used until a DHCP server is located. The subnet mask is set to 255.255.0.0.
The range of IP addresses (from 169.254.0.1 through 169.254.255.254) used for APIPA is reserved by the Internet Assigned Numbers Authority (IANA). Any IP addresses within this range are not used on the Internet.
Go to Start | Settings | Network and Dial-up Connections:
Right-click the network connection for which you want to install and enable TCP/IP, and then click Properties. The following window should appear:
Click Internet Protocol (TCP/IP) | Properties.
Click Use the following IP address, and then select one of the following options:
- For a local area connection, in IP Address, Subnet Mask, and Default Gateway, type the IP address, subnet mask, and default gateway addresses.
- For all other connections, in IP address, type the IP address.
Click Use the following DNS server addresses. In Preferred DNS server and Alternate DNS server, type the primary and secondary DNS server addresses.
To configure advanced settings, click Advanced. The following screen should appear:
Next, do one or more of the following:
To configure additional IP addresses:
- On the IP Settings tab, in IP addresses, click Add:
- In IP Address and Subnet mask, type an IP address and subnet mask, and then click Add.
- Repeat step 1 for each IP address you want to add, and then click OK.
To configure additional default gateways:
- On the IP Settings tab, in Default gateways, click Add:
- In Gateway and Metric, type the IP address of the default gateway and the metric, and then click Add.
- Repeat step 1 for each default gateway you want to add, and then click OK.
To configure a custom metric for this connection:
- Type a metric value in the Interface metric field.
Go to Start | Settings | Network and Dial-up Connections:
Right-click the network connection for which you want to install and enable TCP/IP, and then click Properties. The following window should appear:
Click Properties. The following window should appear:
- If you want to obtain DNS server addresses from a DHCP server, click Obtain DNS server address automatically.
- If you want to manually configure DNS server addresses, click Use the following DNS server addresses, and in Preferred DNS server and Alternate DNS server fields, type the preferred DNS server and alternate DNS server IP addresses.
To configure advanced DNS properties, click Advanced, click the DNS tab, and do one or more of the following:
To configure an additional DNS server IP address:
- Under DNS server addresses, in order of use, click Add.
- In DNS server, type the IP address of the DNS server, and then click Add.
To modify the resolution behavior for unqualified DNS names, do the following:
- To resolve an unqualified name by appending the primary DNS suffix and the DNS suffix of each connection (if configured), click Append primary and connection specific DNS suffixes. If you also want to search the parent suffixes of the primary DNS suffix up to the second level domain, select the Append parent suffixes of the primary DNS suffix check box.
- To resolve an unqualified name by appending the suffixes from a list of configured suffixes, click Append these DNS suffixes (in order), and then click Add to add suffixes to the list.
To configure a connection-specific DNS suffix (local area connection only), type the DNS suffix in DNS suffix for this connection.
To modify DNS dynamic update behavior (local area connection only), do the following:
- To use a DNS dynamic update to register the IP addresses of this connection and the primary domain name of the computer, select the Register this connection's addresses in DNS check box. This option is enabled by default. The primary domain name of the computer is the primary DNS suffix appended to the computer name and can be viewed as the full computer name on the Network Identification tab (available in System in Control Panel).
- To use a DNS dynamic update to register the IP addresses and the connection-specific domain name of this connection, select the Use this connection's DNS suffix in DNS registration check box. This option is disabled by default. The connection-specific domain name of this connection is the DNS suffix for this connection appended to the computer name.
NOTE: To completely disable DNS dynamic update for all names on the computer, clear the Register this connection's addresses in DNS and Use this connection's DNS suffix in DNS registration check boxes for all connections in Network and Dial-up Connections.
Go to Start | Settings | Network and Dial-up Connections:
Right-click the network connection for which you want to install and enable TCP/IP, and then click Properties. The following window should appear:
Click Internet Protocol (TCP/IP) | Properties. The following window should appear:
Click Advanced, then click the WINS tab:
Click Add. In the TCP/IP WINS server window that opens, type the IP address of the WINS server, and then click Add:
Repeat the steps above for each WINS server IP address you want to add, and then click OK.
- To enable the use of the Lmhosts file to resolve remote NetBIOS names, select the Enable LMHOSTS lookup check box. This option is enabled by default.
- To specify the location of the file that you want to import into the Lmhosts file, click Import LMHOSTS:
Select the file in the 'Open' dialog box.
To modify the behavior of NetBIOS over TCP/IP behavior, do the following:
- To enable the use of NetBIOS over TCP/IP, click Enable NetBIOS over TCP/IP.
- To disable the use of NetBIOS over TCP/IP, click Disable NetBIOS over TCP/IP.
- To have the DHCP server determine the NetBIOS behavior, click Use NetBIOS setting from the DHCP server.
NOTE:
- If you are using a DHCP server to allocate WINS server IP addresses, you do not need to add WINS server addresses.
- If you disable NetBIOS over TCP/IP, you may not be able to connect to computers that are running operating systems other than Windows 2000.
- You can no longer configure the NetBIOS scope ID on the WINS tab. To configure
the NetBIOS scope ID, set the following registry value to the name of the scope ID that you want to use:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\NetBT\Parameters\ScopeID
