Occasional problem using Active/Passive Windows Cluster with Message Queuing Role

Hi,

I am experiencing an occasional problem with an Active/Passive Windows Failover cluster and would like to get some help and guidance on how to find the root cause to the problem. The cluster is setup using two Windows Server 2019 with a quorum disc as witness. The cluster has an Message Queuing role and this is where I can see the problem.

When testing the installation everything seems to work as expected on both nodes and even when failing over the functionality is as expected. So far everything seems fine but when using the failover cluster manager every now and then I can see an information message saying "Problem Accessing Client Access Point. For more data see Information Details". When clicking on "Information Details" an error message is displayed stating "Unable to find a Client Access Point dependency for Message Queuing 'MSMQTEST'". This can happen on both nodes and after a refresh the message disappear.

I have no way to reproduce the error but it keeps coming back occasionally. As this is a very critical service in our installation we have a bad feeling and would very much appreciate some input on this error to be able to solve it. We cannot see that this has an negative effect on the functionality in the test environment but when moving to production the workload will be completely different and any problem would be non acceptable.

Is there anyone out there that has experienced a this scenario?
Any suggestions of where to look for any logging that can help in the right direction?

BR,
Stefan

    Hello @stefan ,

    Please check couple of settings in cluster properties: Are you seeing this value as Unchecked? Use network name for computer name

    If so, verify the following registry entries in both nodes

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\<SERVICENAME>\Environment

    If this is presented, you need to manually delete the entry.
    Actually, what happens is when the settings is unchecked, the value is not deleting from Registry.

    Please mark as "Accept the answer" if the above steps helps you. Others with similar issues can also follow the solution as per your suggestion

    Regards,

    Manu
