Microsoft TCP/IP

Microsoft TCP/IP enables enterprise networking and connectivity and provides:

* a standard routable enterprise networking protocol

* access to the worldwide internet and its resources

TCP/IP Configuration

Windows based system needs to be configured with three parameters to use TCP/IP in a routed network environment.

IP Address

An IP address is a logical 32 bit address used to identify a TCP/IP host. Each IP address has two parts – the network Id and the host Id . The network id identifies all hosts that are on the same physical network. The host id identifies a host on the network. Each computer running TCP/IP requires a unique IP address.

Subnet Mask

A subnet mask is used to "mask" a portion of the IP address so that TCP/IP can distinguish the Network ID from the Host ID. When TCP/IP host wants to communicate, the subnet mask is used to determine whether a host is located on a local or remote network.

Default Gateway

-------------------------------------------------

For communicating with a host on another network, an IP address must be configured for the default gateway (synonymous with a router). The default Gateway is where TCP/IP sends packets that are destined for remote networks.

 How to Configure TCP/IP

1. From the desktop, click Start -> Settings -> Control Panel

2. Double-click Network

3. From the list "The following network components are installed", double-click TCP/IP

4. Select Obtain...
