Original product version:   Microsoft Message Queuing
Original KB number:   202124

Introduction

Depending on the type of MSMQ installation, the following information will demonstrate the necessary steps to remove MSMQ. It is important to backup the system prior to performing these steps. Failure to do so may result in the loss of critical files.

Important

This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, see Windows registry information for advanced users.

Remove MSMQ for Windows NT PEC, PSC, BSC, RS, or IC

  1. Stop the MSMQ and the Distributed Transaction Coordinator (MSDTC) services in the Control Panel Services applet.

  2. Stop the Message Queuing Data Access (MQAC) driver. Open a new command prompt window and execute the command:

    net stop mqac

  3. For a site controller (a Primary Enterprise Controller (PEC), Primary Site Controller (PSC), or Backup Site Controller (BSC)), use SQL enterprise manager to delete the Message Queue Information Service (MQIS) database and both MQIS devices (MQISData and MQISLog).

    To ensure that the device has been dropped from the sysdevices table, do the follows:

    1. Run ISQL or SQL Query Analyzer.
    2. Select Master database (default).
    3. Type sp_helpdevice, and then press CTRL+E to execute the query.
    4. In the results, verify if the MQIS devices are present.
    5. If they are present, then type sp_dropdevice MQISData, MQISLog and then execute the query to drop the MQIS devices from the sysdevices table.

  4. Delete the folder where MSMQ is installed. For example:

    C:\Program Files\MSMQ

  5. Delete the following MQ DLLs and files from the C:\Winnt\System32 directory.

    Note

    Not all of the files in the following list will appear in every type of MSMQ installation, these shown are for a PEC.
