Consider the following scenario. You collect data on the following performance counters on a computer that is running Windows Server 2008 or Windows Vista.
Object: Server Work Queues\Current Clients
Instances: SMB2 Blocking [number]
SMB2 NonBlocking [number]
In this scenario, you collect incorrect data. For example, the value of the “SMB2 NonBlocking 0” counter is extremely high (approximately 4,294,967,200). Therefore, you cannot monitor accurately the status of the server.
