Several Network Load Balancing hotfixes that were published before February 1, 2001 replace one or more Network Load Balancing .dll files and cannot be applied simultaneously. The hotfix package that is described in this article provides a set of Network Load Balancing .dll files that contain the hotfixes that were published before February 1, 2001.

The hotfix package that is described in this article resolves the following problems:
  • The Network Load Balancing Windows Management Instrumentation (WMI) provider leaks a significant amount of memory in the WinMgmt process, resulting in 50 megabytes (MB) of memory being leaked in approximately 17 hours.
  • Modifying a host's Load weight setting in the configuration for Network Load Balancing ends all existing client connections to that host through the virtual IP address.
