Choosing installation subcomponents

The following table lists the subcomponents of Message Queuing, the 32-bit Windows Server 2003 family operating systems on which they can be installed, their dependencies on other subcomponents, and their names in the .inf file.

Note

  • On 64-bit platforms, the Core and Local Storage subcomponents are combined in a single subcomponent, called Common, which in this case, provides independent client functionality.

Default options

When you select Message Queuing in the Windows Components Wizard on computers running on platforms from the Windows Server 2003 family, the following subcomponents are selected by default:

  • Common (consisting of Local Storage and Core)

  • Local Storage

  • Active Directory Integration

This means that, by default, an independent client capable of integrating with Active Directory (whenever the computer belongs to a domain) will be installed on computers running Windows Server 2003 family operating systems.

If a computer belongs to a workgroup, the Active Directory Integration subcomponent is selected by default. In workgroup mode, the presence of this subcomponent means that the computer will allow for the possibility that it joined a domain and will try to integrate with Active Directory each time the Message Queuing service is started (that is, it will attempt to create an msmq object in Active Directory, and so on). As long as the computer remains in workgroup mode, no msmq object is created in Active Directory, only direct messages can be sent, and only private queues can be created or deleted.

Computers running on 64-bit platforms

A dependent client cannot be installed on a computer running on a 64-bit Windows Server 2003 family platform. Therefore, we can simplify the list of Message Queuing subcomponents for 64-bit computers by combining the Core and Local Storage subcomponents into a single Common subcomponent, and we do not need two levels of Message Queuing subcomponents. The subcomponent tree for 64-bit computers has the following form:

Message Queuing

Line graphicTriggers

The Routing Support and Downlevel Client Support subcomponents are available only on platforms from the Windows Server 2003 family. Furthermore, Downlevel Client Support can be installed only on a domain controller. If only the Core subcomponent is selected, an independent client will be installed.

Registry keys

A registry key is created in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Setup for each subcomponent installed, and its value is set equal to 0x1. It indicates that the applicable subcomponent was installed successfully on the computer. The absence of a key means that the subcomponent was not installed. The following list gives the names of these registry keys:

  • msmq_Core

  • msmq_LocalStorage

  • msmq_ADIntegrated

  • msmq_TriggersService

  • msmq_HTTPSupport

  • msmq_RoutingSupport

  • msmq_MQDSService
