Symptoms

Consider the following scenario:

  • You have a computer that is running one of the following operating systems:

    • Windows Vista
    • Windows Server 2008
    • Windows 7
    • Windows Server 2008 R2
  • You share some files or some folders on the computer.

  • Some users try to access the shared files or the shared folders from remote computers.

In this scenario, the computer that shares the files and the folders may temporarily not respond to file share requests. When this issue occurs, users cannot enumerate the shared files or the shared folders on the computer.

Note The computer that shares the files and the folders resumes responding to requests for shared resources after 4 minutes.

Cause

This issue occurs because the Server Message Block (SMB) worker thread that handles SMB requests is not available. This causes the computer not to respond to SMB requests. Therefore, you experience the issue that is described in the "Symptoms" section.

Resolution

Note You need to apply the hotfix package on the computer which shares files.
