If you select Typical Settings when installing Windows 2000, TCP/IP is installed for you. But you’ll still need to know how to install network protocols. You may want to install different protocols, and Microsoft’s MCP exams are certain to stress the use of TCP/IP.
In last week’s IT Certification Corner, I examined the installation and configuration of a network client and network services. This week, I’ll explain the installation and basic configuration of network protocols.
Installing network protocols
When you need to install or reinstall TCP/IP or install another protocol, begin by selecting Start | Settings | Network And Dial-Up Connections. Right-click the connection you want to configure and select Properties.
Look for the protocol you want to use in the Components Checked Are Used By This Connection box, shown in Figure A. If the protocol isn’t listed, you’ll need to add it. It’s possible, too, that the protocol has already been added but has been configured improperly.
|Check before installing a protocol to ensure it hasn’t already been loaded.|
Make sure the network client and service are installed, then click Install. From the pop-up menu, double-click Protocol. Alternatively, you can click Protocol and click the Add button. Since most enterprises rely upon TCP/IP, that’s the protocol I’ll install in this example.
From the Select Network Protocol dialog box, shown in Figure B, double-click Internet Protocol (TCP/IP) or select Internet Protocol (TCP/IP) and click OK. Both actions will select the TCP/IP option.
Other protocol options are provided by default. They are:
- Network Monitor Driver
- NWLink IPX/SPX/NetBIOS Compatible Transport
|In the Select Network Protocol dialog box, specify the protocol you want to install.|
If you want to use a protocol that’s not listed, click the Have Disk button. You’ll be prompted to point to the location of the protocol, whether it’s on a hard disk, a network share, a floppy or removable drive, a CD-ROM, or DVD.
After installing the protocol, make sure the check boxes are selected for the network client, service, and protocol. The next step is to configure basic protocol settings.
If the system is to receive an IP address automatically from a DHCP server, you can simply click Close and reboot. When rebooting, the system will send out a DHCP discover message. The DHCP server will snag that message off the network and fire back an IP address and subnet mask, an address for DNS services, and a default gateway (if the DHCP server is so configured).
Specifying static IP addresses
If you want to specify a static IP address, click on the protocol you want to configure and select Properties. In the General tab, select the Use The Following IP Address option, as shown in Figure C.
|To specify an IP address, you’ll have to provide the associated subnet mask, default gateway, and DNS server addresses.|
Once you’ve entered the IP address and its associated subnet mask, along with the addresses for the default gateway and DNS servers, click OK. When entering IP addresses, type periods to separate your dotted-decimal entries. Use the [Tab] key to move from box to box.
After you’ve provided the necessary addresses, you can specify any WINS servers you want to use by clicking the Advanced button. Click on the WINS tab, enter the WINS server address, then click OK.
In the WINS tab, you can also specify whether to enable LMHOSTS lookup and NetBIOS over TCP/IP. You can also specify that the NetBIOS configuration be set based on a DHCP server setting. Click OK once you’ve set these values.
Click OK, click OK again, and click Close. Finally, close the Network And Dial-Up Connections box, and you should find your network connection working properly.
You can learn more about your network settings by running the IPCONFIG command. Do so by clicking Start | Run. Type cmd and click OK. Then, type IPCONFIG /ALL. The details of your network adapters will be displayed. You can use this information to further troubleshoot errors on your network. It will at least lend confidence that all network adapters are configured properly.
