Dear Doug,
thank you for your reply and sorry for a delay with the feedback.
I am not sure what I have to troubleshoot, I am unable to see any error or malfunction on remote server, all event logs are clear.
(It’s 2016 server with SQL Server running on it, so WMIDIAG is not applicable). Checked winmgmt /verifyrepository, it says WMI repository is consistent.
As this is a production server, rebuilding WMI Repository is out of question. Do you probably have some other ideas?
