Summary

The Network Load Balancing (NLB) driver on the host tracks connections to maintain client/network affinity configured on the NLB cluster. If the driver is not functioning properly, NLB may not be able to track TCP connections or may experience load distribution errors.

Causes
This rule does not contain any causes.
Resolutions

Manage memory resources on the NLB host

If the Network Load Balancing (NLB) driver cannot allocate enough memory resources to operate the driver, you should close all programs on this cluster host that might be consuming memory, and then rebind NLB to the adapters. If this problem persists, you might need to add additional memory (RAM) to this host.

To manage memory resources on the NLB host:

  • Determine which programs are consuming excessive amounts of memory on the host by using Task Manager.

  • If possible, close the program, and then rebind NLB to the adapter.

  • If the problem persists, you should add additional memory (RAM) to the host.
