Abstract
This chapter focuses on “Troubleshooting Windows 2000 IP Addressing Problems,” and routing decisions. In Windows 2000 Server, the Routing and Remote Access Service (RRAS) is a full-featured software router that provides an open platform for routing and inter-networking. RRAS is fully integrated with the operating system and can be extended with application programming interfaces (APIs) that allow developers to construct customized networking solutions. The difference between direct routing and indirect routing are discussed and the concept of a default gateway is examined in the chapter. Windows 2000 helps in assigning multiple default gateways to a network interface, which function as “backup” gateway routes if the first gateway goes down. A Windows 2000 router can be connected to one or more subnets via network interface cards (NICs), modems, Integrated Services Digital Network (ISDN) terminal adapters, or other wide area network (WAN) connection devices. A Windows 2000 multihomed host computer is configured as an IP router to provide packet forwarding for other transmission control protocol/internet protocol (TCP/IP) computers by enabling the RRAS service and setting up a routed IP network. This can be a static routed network, a Routing Information Protocol (RIP) for IP routed inter-network, or an Open Shortest Path First (OSPF) routed inter-network. The Windows 2000 router supports both RIP (versions 1 and 2) and OSPF dynamic routing protocols.
