What is the old Method used to retrieve drive space information in the "Exchange Information Stores" task.
Answer:
When WMI fails, the code in QSMailboxStats.DLL that generates the event falls back to the Windows Network Management API that is used by Windows Explorer and the NET command to manage network shares. The code does information level 2 NetShareEnum() calls to retrieve information about shares on the server. The code looks for administrative drive shares like C$, D$, and E$. For each administrative drive share, the Volume Management API function GetVolumeInformation() is used to get information about the volume behind the drive share.
