SYMPTOMS

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.

CAUSE

The Server service maintains some queues for client connections that use the Server Message Block (SMB) 2.0 protocol. However, the counts of these queues are not managed very well when connection information is moved across these queues. This behavior causes the incorrect updates of queue counts. In the scenario that is mentioned in the "Symptoms" section, the SMB 2.0 performance counters increase incorrectly to extremely high values.

RESOLUTION
