SUMMARY
The following registry parameters can be modified to change the behavior of Windows NT Load Balancing Service (WLBS).

Default = 1000

Specifies the period in milliseconds between "I am alive" status messages broadcast by each host.

AliveMsgTolerance

Data type = REG_DWORD

Range = 5 - 100

Default = 5

Specifies the number of periods to wait after the last message from a host before it is declared dead.

ClusterIPAddress

Data type = REG_SZ

Specifies the IP address of the WLBS cluster (also configurable through the GUI).

ClusterName

Data type = REG_SZ

Specifies the name used of the WLBS cluster (also configurable through the GUI).

ClusterNetworkAddress

Data type = REG_SZ

Specifies the media access control address used by the WLBS cluster (also configurable through the GUI).

ClusterNetworkMask

Data type = REG_SZ

Specifies the network mask used by the WLBS cluster (also configurable through the GUI).

ClusterModeOnStart

Data type = REG_DWORD

Range = 16 - 1024

Default = 512 Specifies the number of connection descriptors allocated at a time.

HostPriority

Data type = REG_DWORD
