How to determine whether MSMQ is in Domain Mode or not

Question

How do I check if Microsoft Queueing MSMQ has been installed in Domain Mode or not?

Answer 1

Important - installing AD support for MSMQ does NOT mean MSMQ will be automatically AD integrated. For example, if installing under an account without sufficient domain admin privileges. From my blog

Note - if you want to verify that MSMQ is actually Active Directory Integrated (not just that Active Directory is installed), you want to check:

•HKLM\Software\Microsoft\MSMQ\Parameters\Workgroup (value should be 0 or not present)

•HKLM\Software\Microsoft\MSMQ\Parameters\Setup\CreateMsmqObj (value should exist and be 0; the absence of this key doesn’t necessarily indicate a problem)

The HKLM\Software\Microsoft\MSMQ\Parameters\Workgroup value can be missing if MSMQ Active Directory Integration is installed and MSMQ is successfully operating in domain mode. The presence of this value depends on whether Active Directory Integration was installed before or after the machine was joined to the domain, and whether MSMQ has previously had any failures in contacting the domain controller. Regardless, this key only indicates a problem if its value is 1 and MSMQ is supposed to be Active Directory Integrated

Answer 2

You should be able to view the installed components, e.g. for Windows 2012 R2:

• Manage Server
• Add Roles and Features
• Next until "Select Features"
• OPen "Message Queuing" -> "Message Queueing Services"

If "Directory Service Integration" is enabled, MSMQ is in Directory (Domain) Mode.
