Some private queues may not appear or may disappear when you update the view in the Computer Management window (839928)


The information in this article applies to:

  • Microsoft Message Queuing 2.0

SYMPTOMS

Some private queues may not appear in the Computer Management window. Additionally, after you create several private queues, and then you update the view in the Computer Management window, you may notice that some private queues disappear.

CAUSE

This problem occurs because one or more of the local queue storage (LQS) files on your computer is corrupted. This problem occurs for the private queues that correspond to the corrupted LQS files. This problem also occurs for all private queues that are created after the private queues that correspond to the corrupted LQS files.

Note Each private queue on your computer has an associated LQS file.

WORKAROUND

To work around this problem for the private queues that have uncorrupted LQS files, you must remove the corrupted LQS files from the LQS folder. To do this, follow these steps:
  1. Open the Computer Management window. To do this, follow these steps:
    1. Click Start, and then click Run.

      The Run dialog box appears.
    2. In the Open box, type compmgmt.msc, and then click OK.

      The Computer Management window appears.
    3. In the Computer Management window, expand Services and Applications in the left pane, expand Message Queuing, and then click Private Queues.

      Notice that some private queues do not appear in the right pane of the Computer Management window.
  2. Start Microsoft Windows Explorer.
  3. Locate the %WINDIR%\System32\msmq\STORAGE\LQS folder.

    Note The LQS files on your computer exist in the %WINDIR%\System32\msmq\STORAGE\LQS folder. The placeholder %WINDIR% is a placeholder for the absolute path of your Microsoft Windows folder.
  4. Add all the LQS files from the LQS folder to a temporary folder.
  5. Add an LQS file from the temporary folder to the LQS folder.
  6. Switch to the Computer Management window.
  7. In the left pane of the Computer Management window, right-click Private Queues, and then click Refresh.

    If a new private queue does not appear in the right pane of the Computer Management window, the LQS file that you moved in step 5 is corrupted, and you must move this LQS file to another temporary folder.
  8. Repeat steps 5 through 7 until there are no LQS files in the first temporary folder.

    The problem that is mentioned in the "Symptoms" section does not occur for the private queues that correspond to the uncorrupted LQS files.
Note If you have a limited number of queues, an easier way to find the problem file is to open each LQS file in Notepad. If the format does not match the one that is listed, the queue is causing the problem. Frequently, the corrupted LQS file is blank or is missing whole sections.

STATUS

This behavior is by design.
