24.3 Conﬁguration of the servers in the cluster

NLB conﬁguration for Server2

The conﬁguration is almost the same in the case of Server1. However, IP address of the server is diﬀerent (192.168.1.20) and it is also necessary to select diﬀerent priority for the server (e.g. 2).

Note: The problem of cluster settings for load balancing is too wide and complicated to be described in this manual. Detailed information can be found at Microsoft’s technical support Web site:
