Unable to enumerate clustered MSMQ Queues using PowerShell or C# console application

Question

I'm trying to use the following MSMQ PowerShell CmdLets to access the Clustered MSMQ Queues:

Get-MSMQQueue
Get-MSMQQueueACL

I've tried running the scripts from both the active and standby nodes of the cluster and I'm not able to see the queueus or ACLs.

I've also set the environment variables as follows before running with the same result.

$env:computername = "MsmqHostName"
$env:_CLUSTER_NETWORK_NAME_='MsmqHostName'
$env:_CLUSTER_HOST_NAME_='MsmqHostName'

As well as:

$env:CLUSTER_NETWORK_NAME='MsmqHostName'
$env:CLUSTER_HOST_NAME='MsmqHostName'

In addition; I developed a C# console app using P/Invoke of the MSMQ related APIs.

I am able to enumerate the queues and ACLs for local MSMQ, but I'm not able to enumerate them for the clustered queues.

Anyone know what I can do to enumerate the clustered queues using either PowerShell or from my C# console application?

Thank you.

Answer 1

I was able to enumerate the queues and ACLs using the messaging APIs from a C# console application. To get the ACLs; I had to use P/Invoke on the platform APIs.

Calling the MSMQ APIs for clustered queues/ACLs does require the '_CLUSTER_NETWORK_NAME_' environment variable to be set to the cluster host name. (NOTE: CLUSTER_NETWORK_NAME is prefixed and suffixed with '_')

Because the server is running Windows Server 2012, I suspect the PowerShell scripts may not work.

In Windows Server 2019, there are Failover Cluster Management Tools PowerShell extensions that may work.
