SYMPTOMS
When you click Explain to receive information about the Current Commands counter for the Redirector performance object, the following definition appears. This definition contains incorrect information:

Current Commands counts the number of requests to the Redirector that are currently queued for service. If this number is much larger than the number of network adapter cards installed in the computer, then the network(s) and/or the server(s) being accessed are seriously bottlenecked.

To locate this information, follow these steps.

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
 * 1) Start the Windows Performance tool.
 * 2) Click the Add button, and then click Redirector in the Performance object list.
 * 3) In the Select counters from list list, click Current Commands, and then click Explain.



MORE INFORMATION
The following information correctly explains the Current Commands counter for the Redirector performance object:
 * The number of commands that is indicated by the Current Commands counter is not related to the number of network adapters that are installed in the computer. This counter indicates the number of pending commands that are waiting to be serviced by the local computer.
 * The Current Commands counter indicates the number of pending commands from the local computer to all destination servers. This means that if one of the destination servers does not respond in a timely manner, the number of current commands on the local computer may increase.

If the local computer is serving many sessions, a high number of current commands does not necessarily indicate a problem or a bottleneck. However, if the Current Commands counter shows a high number and the local computer is idle, this may indicate a network-related problem or a redirector bottleneck on the local computer. For example, there may be a network-related problem or a local bottleneck if the computer is idle overnight but the counter shows a high number during that period.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
