Symptoms

When you try to connect to network shares that are hosted on a Microsoft Windows 2000-based server, one or more of the following symptoms occur:
  • The following event appears in the system log on the client computer:

    Event ID: 3013
    Event Type: Error
    Event Source: MrxSmb / Rdr
    Description: The redirector has timed out a request to ComputerName.

  • You receive an error message that is similar to one of the following messages when you try to connect to a shared resource:
    System error 53. The network path was not found.
    System error 64. The specified network name is no longer available.
  • You are intermittently disconnected from network resources, and you cannot reconnect to the network resources on the file server. However, you can ping the server, and you can use a Terminal Services session to connect to the server.
  • If multiple users try to access Microsoft Office documents on the server, the "File is locked for editing" message does not always appear when the second user opens the file.
  • A network trace indicates a 30-second to 40-second delay between an SMB Service client command and a response from the file server.
  • When you view the system event log in Event Viewer on the Windows 2000-based server, you see that the following event has been logged close to the time when a client was not able to connect to a network share:

    Event ID: 2022
    Source: Srv
    Description: Server was unable to find a free connection NumberOfTimes times in the last NumberOfSeconds seconds.

  • If the Windows 2000-based server that is affected is part of a cluster, the server may also report an Event ID 4, an Event ID 1055, and an Event ID 4322, in addition to Event ID 2022 in the system event log.

Cause

This problem may occur if server service connections cannot allocate sessions. In this scenario, the problem occurs when the thread that is responsible for allocating and for cleaning up sessions is blocked by a device driver during the cleanup routine.

The hotfix that is described in the "Resolution" section of this article corrects the problem in the case where server service connections cannot allocate sessions. However, there are other potential causes for an Event 2022 to be logged.
