Troubleshooting Load Balancing In Windows
Symptom
Tip
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 and 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 the dedicated IP address of a
load balancing group, change one of the IP addresses.
See “
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.
