Receive load balancing fails to begin 
functioning.

Check the Group Properties to verify that the dedicated IP 
address has been entered. If no address appears in the 
Group Properties dialog box, enter one to enable receive 
load balancing.

Receive load balancing stops 
functioning.

Cables may be disconnected, or there may be other 
hardware problems. Reconnect or change the cables. 
Correct any other hardware problems. Bidirectional load 
balancing is restored after this type of failure when 
applications create new connections or new clients log in.

Reconnecting cables does not restore 
load balancing.

Check the event log for a duplicate IP address. If another 
device is using a load balancing group's dedicated IP 
address, change one of the IP addresses. See “Changing an 
IP Address” on page 48 for instructions.

Receive load balancing does not 
function across a router.

Receive load balancing across a router is not supported. 
Clients across the router cannot use receive load balancing, 
but clients within the subnet get higher throughput from 
receive load balancing.
