The Microsoft® Exchange Server Analyzer Tool tries to query the Win32_PingStatus Microsoft Windows® Management Instrumentation (WMI) class to analyze the response object for various mail-flow-specific configuration settings.

Win32_PingStatus typically returns an object that has 24 properties that supply extensive details about the ping packets that the class sends.

If the Exchange Server Analyzer does not receive the expected object in response to its query after six consecutive attempts, the Exchange Server Analyzer displays a warning.

This warning indicates that the Win32_PingStatus could not be performed.

The most likely cause of this failure is that the computer that tries to execute the Win32_PingStatus command is running on the Microsoft Windows® 2000 Server operating system. Windows 2000 Server does not support the Win32_PingStatus WMI class.

If the computer that tries to execute the Win32_PingStatus command is not running on the Windows 2000 Server operating system, the issue could be the result of general networking issues or a permissions problem.

To correct this error

  1. Make sure that the Exchange Server computer has been started and is connected to the network.

  2. Use the PING command from the computer that is running the Exchange Server Analyzer to see whether the target Exchange Server computer is reachable.

  3. Use the PING command from a server that is on the same subnet with the target Exchange server to see whether the target Exchange Server computer is reachable.

  4. If there is a firewall, check to see whether remote procedure call (RPC) ports are blocked.

  5. Examine the permissions for the account under which the Exchange Server Analyzer is running. The account under which the Exchange Server Analyzer is running must have local Administrator permissions on each Exchange server that it scans.
