System.Management.ManagementException: Invalid namespace

A possible solution was discussed in the Microsoft technet here.
Changing system files without the advice from Microsoft might be risky. Keep that in mind!
The steps needed as discussed in the technote are:
1.) browse “C:\Program Files\Microsoft\Exchange Server\V15\Bin”
2.) edit the file Microsoft.Exchange.Diagnostics.Service.exe.config
3.) search for DriveLockCheckEnabled
4.) Change the word true to false so that it will looks like:
<add key=”DriveLockCheckEnabled” value=”false” />
5.) Restart the Microsoft Exchange Diagnostics service.
