 * SUMMARY
 * Configuring the IP Addresses on the Network Adapter



SUMMARY
This article describes how to properly configure IP addresses with Network Load Balancing. The following criteria must be true before you follow the steps in this article.
 * A computer running Windows 2000 Advanced Server with NLB installed on a single network adapter.
 * The virtual (cluster) IP address is 192.168.0.100 and uses the subnet mask 255.255.255.0.
 * The dedicated IP address is going to be 192.168.0.1 with the subnet mask 255.255.255.0.

Configuring the IP Addresses on the Network Adapter

 * 1) Click Start, point to Settings, click Control Panel, and then double-click Network and Dial-up Connections.
 * 2) Right-click the network adapter, and then click Properties.
 * 3) Click to select the Network Load Balancing check box.
 * 4) Click Network Load Balancing, and then click Properties.
 * 5) On the Cluster tab, type the cluster's IP address in the Primary IP address box, and then type the appropriate subnet mask.
 * 6) On the Host Parameters tab, type the dedicated IP address and the appropriate subnet mask.
 * 7) Click OK.
 * 8) Click Internet Protocol (TCP/IP), and then click Properties.
 * 9) Click Use the following IP address, and then type the virtual IP address in the box.
 * 10) Verify that the advanced properties of TCP/IP display the virtual IP and the Primary IP address under the IP settings, IP address (both IP address should be listed).
 * 11) Click OK twice to close the properties for that network adapter.

The server is now configured to accept connections to the virtual address and load balances with other servers if they are configured similarly.

NOTE: The dedicated IP address must be unique between all NLB cluster members. The virtual address is the same.
