More Information

Depending on the type of MSMQ installation, the following information will demonstrate the necessary steps to remove MSMQ. It is very 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 Microsoft Windows NT Primary Enterprise Controller (PEC), Primary Site Controller (PSC), Backup Site Controller (BSC), Routing Server (RS), or Independent Client (IC):

    1. Stop the Microsoft Message Queue and the Microsoft Distributed Transaction Coordinator (MSDTC) services in the Control Panel Services applet.
    2. Stop the MQAC driver. Open a new command prompt window and execute the command:

      net stop mqac
    3. For a site controller (a PEC, PSC, or BSC), use SQL enterprise manager to delete the MQIS database and both MQIS devices (mqisdata and mqislog).

      To ensure that the device has been dropped from the sysdevices table, do the following:
      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 DLL's 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):
