The Microsoft® Exchange Server Analyzer Tool queries two Microsoft Windows® Management Instrumentation (WMI) classes to do the following:


The Bind registry value is a multi-string value that contains a list of network adapters in binding order. The first entry in the list is the first bound network adapter; the second entry is the second network adapter in the binding order; and so forth.

If the Exchange Server Analyzer determines that the cluster heartbeat network adapter is first in the binding order, a warning is displayed.

To resolve this problem, make sure that the public network adapter is the first binding at the top of the binding list. If you have multiple public network adapters, make sure that the private heartbeat network adapter is listed last. If the heartbeat network adapter is listed first, it can prevent the correct installation of service packs and upgrades.

To correct this warning

  1. In the Network Connections window, click Advanced, and then click Advanced Settings.

  2. Click the Adapters and Bindings tab.

  3. In the Connections field, select the private network adapter and use the down arrow to move the private network adapter to the bottom of the list.

  4. Repeat these steps for each node in the cluster.
