How to Configure Network Protocol? But first of all what is network protocols?
Networking protocols are a set of standards or language used by PCs to communicate or to package and transmit data over a network.
The protocol determines how the information is divided into packets, how it is addressed, and what is done to assure it is reliably transferred.
Therefore, protocol is very important to the success of networking. TCP/IP is the most common Windows network protocol. It is the default protocol used when installing networking capabilities on all recent Windows operating systems.
Windows 7 offers three Internet protocols and two network-mapping protocols:
Internet Protocol Version 4 (TCP/IPv4) - use with the Internet and most LANs
Internet Protocol Version 6 (TCP/IPv6) - latest and use with the widest variety of networks
Reliable Multicast Protocol - a special one-to-many protocol used in conferencing
Link-Layer Topology Discovery Mapper I/O Driver that goes out and finds devices on the network
"Link-Layer Topology Discovery Responder that responds when it is queried by a Discovery Mapper
All of these protocols, except Reliable Multicast Protocol, are installed by default. If the computer you are working on is or will be connected to the Internet, it will require TCP/IPv4.
So, you need to check (and change if necessary) the protocols that have been installed and the settings that are being used.
To check and change protocols
Click Start and click Control Panel.
In Category view, click Network and Internet, and then click Network and Sharing Center.
From the Network and Sharing Center window displayed, under the View your active networks section, click Local Area Connection in the middle-right area.
From the Local Area Connection Status dialog box displayed, it shown that the computer is connected to the network and that it is sending and receiving data, which indicates it is correctly set up.
Click Properties button.
From the Local Area Connection Properties dialog box displayed, it appears and displays the services and protocols that have been installed automatically.
Click Install button.
From the Select Network Feature Type dialog box displayed, double-click on Protocol.
If you see any protocol you want installed, double-click it. Otherwise, click Cancel twice to close the Select Network Protocol and Select Network Feature Type dialog boxes.
Select the Internet Protocol Version 4 (TCP/IPv4) protocol in the Local Area Connection Properties dialog box, and click Properties button.
From the Internet Protocol Version 4 (TCP/IPv4) Properties dialog box displayed, you can either use a dynamic IP (Internet Protocol) address automatically assigned by a server or DSL router, or to enter a static IP address in this dialog box.
To obtain an IP address automatically, just leave the default settings and click the OK button.
To enter your own IP address, click the Use the following IP address: option and enter an IP address. The IP address that you use should be from the block of IP addresses that an Internet Service Provider (ISP) has assigned to your organization.
If you entered a static IP address, you must also enter a Subnet mask and Default gateway. If you used the APIPA range of addresses, use 255.255.0.0 as the subnet mask.
Also, if you enter your own IP address, normally you also need to enter the DNS server addresses. For more information, please refer to your country ISP.
Once finish, click OK.
Click Start, click the Shut Down right arrow, and click Restart. This is required to utilize your network settings.
To verify your connection
Click Start and click Control Panel.
In Category view, click Network and Internet, and then click Network and Sharing Center.
From the Network and Sharing Center window displayed, under the View your active networks section, click Local Area Connection in the middle-right area.
From the Local Area Connection Status dialog box displayed, you should see activity on both the Sent and Received sides. The computer is networked.
" If you do not see both sending and receiving activity, you need to double-check all the possible settings:
- If you are using APIPA, make sure that the computer you are trying to contact is also using that range of numbers, either as a static assigned address or with automatic assignment.
- If all the settings are correct, check the cabling by making a simple connection of just several computers.
- If you do a direct connection between two computers, remember that you need a special crossover cable with the transmitting and receiving wires reversed.
- If all else fails, replace the NIC.
- It could also be that network security is getting in your way of seeing the drives and resources on the other computer.
With a good NIC, good cabling, the correct settings, and network security properly handled, you'll be able to network.
Windows 7 provides two services, both of which are automatically installed:
- File and Printer Sharing For Microsoft Networks handles the sharing of resources on your computer.
- QoS (Quality of Service) Packet Scheduler helps balance a network and alleviate bottlenecks when one part of the network is fast and another part is slow.
