XFOR: LinkAge Queue Viewer Is Not FIFO

The LinkAge Queue Viewer, located in the Microsoft Exchange Administrator program under Connector Properties for any LinkAge Connector, does not give a "First In First Out" (FIFO) view of the queue. To see messages at the top of the queue (or in other words, in FIFO order), you must use MDBVU32 utility.

The Linkage Queue Viewer displays messages in alphabetic order of the originator's name. Hence, if a message from Elizabeth Boyle is sent at 10:21a.m., and a message from Amy Anderson is sent at 2:35 p.m. on the same day, Amy Anderson's message will appear at the top of the queue in Queue Viewer. Therefore, if you suspect that a message in the LinkAge queue is blocking other traffic, and you wish to remove the oldest message from the queue (the message at the top of the queue), you won't be able to easily determine which message is the oldest by simply looking in Queue Viewer. The following articles in the Microsoft Knowledge Base suggest removing the message from the top of the LinkAge queue without taking into account that the LinkAge Queue Viewer does not show these messages in FIFO order: If the messages are currently "stuck" in the MTS-IN, MTS-OUT, READY-IN, or READY-OUT folders of the connector, you must use Mdbvu32.exe to view the contents of these folders in FIFO order. For general instructions on using Mdbvu32, see the following article in the Microsoft Knowledge Base: However, you should note that Profinst.exe will not work for creating a profile to log on to the LinkAge Connector mailboxes. To create a profile for using Mdbvu32, follow these steps:

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

1. Log on to Windows NT as the service account that runs LinkAge Connectors.
2. Using Regedt32, locate the following key:
   

     
         KEY_CURRENT_USER\Software\Microsoft \Windows NT\Windows Messaging
         Subsystem\Profiles.
      
   						

   
   NOTE: The above registry key is one path; it has been wrapped for readability.
3. Find a profile of the pattern: SERVERNAME-LME-CONNECTOR Vn.n (where "n" is the version number). For example: SERVER1-LME-SNADS V5.5.
4. Highlight that profile, and from the Registry menu, click Save Key. Save the key in a directory where you can find it easily.
5. Now highlight the Profiles key. From the Edit menu, click Add Key.
6. In the Add Key dialog box, enter a unique Key Name, like SNADS-Test. Leave the Class field blank, and click OK.
7. Highlight the newly created profile, and from the Registry menu, click Restore.
8. Select the key that was saved in step 4, and click Open.
9. Click Yes on the warning. The profile is now created.

It is recommended that after you identify the message at the top of the folder you are troubleshooting, you use the Queue Viewer in the Exchange Administrator program to first export the message, and then "NDR" the message by selecting the message and clicking the NDR button on the toolbar. This will save the offending message in Transport Neutral Encoding Format (TNEF) format.
