PowerShell error when upgrading to 2020 R2 "Access to Message Queuing system is denied."

[GopalRaghvani]

I am completing the configure part of the upgrade and getting error related to MSMQ. I have also raised a case.

Running ".\Config.ps1 "Config\FNMS Windows Authentication Config.xml" updateconfig"

Getting error:

Completed step Configure BusinessReportingAuthentication virtual directory.

Executing step Create MSMQ queues.
MSMQ is already installed
MSMQ-Services is already installed
MSMQ-Server is already installed
Queue exists but its transactional state () is different to the expected (True). The queue will be recreated.

Hi,

It sounds like the message queues might have been created with another user. The FNMS config script sets the service account as "Full Control". Please check the queues in Computer Management and see if you can change the user permissions.

Adding permission afterwards can be tricky (if your current account doesn't have rights). Maybe uninstalling the message queuing from the server does the trick? The script should automatically re-install the feature.

Best regards,

Markward

I had to delete the queue files from C:\Windows\System32\msmq\storage\lqs
I then reran the script, this time it recreated the queues but failed. I reran the script again and it worked.

I agree with @mfranz , either your service account should have Full Control/Access to MSMQ

or uninstall  the MSMQ by browsing > Server Manager > Manage > Remove roles or features

Then re-run power shell scripts, it should create MSMQ without any errors
