Getting WMI error while installing MABS even though service is running.

Question

Hi,

Let me give you system overview first. I am running windows server 2019 as Domain Controller I am running Hyper-V virtual machine as SQL server. So, in that SQL Hyper-V I am trying to install MABS to take backup of SQL database to the Azure.

I am getting WMI service error on the installation step of Microsoft Azure Backup Server as you can see in the screenshot. Though, my WMI service is running and I even tried to restart it and run the setup again but same issue.

I also tried to look for other solution as per the below article but that did not help me. MABS v4 fail to install on Windows server 2019 - Setup cannot query the system configuration - Microsoft Q&A

DpmSetup.log

Please also see the data protection manager error log given by the MABS setup.

Thanks,

Hello Akram Shaikh,

Thanks for posting your question in the Microsoft Q&A forum.

Run the following commands as an administrator to verify and repair the WMI repository:

winmgmt.exe /verifyrepository
winmgmt /salvagerepository
winmgmt.exe /resyncperf

If the repository check doesn't resolve the issue, try rebuilding the WMI class structure:

wmiadap /c
wmiadap /f
wmiadap /r

The error might be related to Group Policy settings. Check the Deny access to this computer from the network policy in Local Group Policy Editor. Remove any local accounts from this policy and update the policy on the MABS server.
