|Message:||NLB Cluster %2 %1: Dedicated network mask %3 is invalid. The driver will ignore the dedicated IP address and network mask. Please check the NLB configuration and make sure that the dedicated network mask consists of four decimal byte values separated by dots. %4|
This event is logged when the subnet mask entered for the dedicated IP address is not valid. The cluster will continue to operate. However, you cannot use the dedicated IP address, so you cannot use it to manage the host or for other non-cluster-related communication.
No user action is required. The cluster will continue to operate. However, if you want to use the dedicated IP address, enter a valid subnet mask. For more information about entering a subnet mask in Network Load Balancing, see Help and Support.
