Neighborhood and select Properties. On the Protocols tab, select TCP/IP Protocol
and click Properties and then click Advanced.

in the IP Addresses region and clicking Remove. This removes the IP addresses
corresponding to the Web Site.

Simultaneously reboot all the systems in the cluster. Note that you do not want to
eboot them one at a time or they will failover.
ClusterCATS assigns the IP addresses dynamically to your Web servers.
