Event ID 2201 — Trigger Initialization

Event ID 2201 — Trigger Initialization

Updated: January 31, 2008

Applies To: Windows Server 2008

Message Queuing Triggers is a service that you can use to associate the arrival of each incoming message at a queue with a response that depends on the contents of the message. The response may invoke either a Component Object Model (COM) component or a stand-alone executable program. These components or programs can define business rules that can be invoked in response to such messages, without any additional programming. If trigger initialization fails and the trigger service is not available, any trigger-dependent message processing logic will not be carried out.

Confirm registry key and permissions

Message Queuing needs full permission on its registry node. The Message Queuing Triggers service will fail to start if Message Queuing is not able to read certain information from the registry.

You must run the registry editor as an administrator, which is the only way to edit registry keys with the user interface (UI). By default, local administrators have full permissions on the entire registry.

To confirm the registry key and permissions:

Caution: Incorrectly editing the registry might severely damage your system. Before making changes to the registry, you should back up any valued data.

  1. Open Registry Editor. To open Registry Editor, click Start. In the search box, type regedit, and then press ENTER.
  2. Expand HKEY_LOCAL_MACHINE, expand SOFTWARE, expand Microsoft, and then expand MSMQ.
  3. Confirm that the Triggers registry key is available and that Message Queuing can read the registry values.
  4. Right-click the MSMQ Registry node (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ), and then click Permissions.
  5. In Group or user names, confirm that MSMQ is included. If it is not included, click Add.
  6. In Group or user names, click MSMQ, and then click Advanced.
  7. In Permission entries, click MSMQ, and then click Edit.
  8. For Full Control, confirm that MSMQ has the Allow check box selected. This action selects all the other Allow check boxes.
  9. In the Apply to list, confirm that This key and subkeys is selected.

If you continue to receive this error, note any details in the event message, and then contact Microsoft Customer Service and Support (CSS). For information about how to contact CSS, see Enterprise Support http://go.microsoft.com/fwlink/?LinkId=52267).
