Initial Configuration Tasks
First, you have to know what the default gateway address for your LAN segment is. This might mean talking to your network administrator. Usually this address is set automatically by the DHCP protocol, so you don't need to do anything. If you are using a set of static addresses, then you can specify the default gateway address in one of the Windows network dialog boxes. For Unix/Linux, the 'ifconfig' command allows you to set the default gateway address. For server 2008 (including Server 2008 Core) use the netsh command to set the default gateway address (if not using DHCP).
