    The error 40002 could be reported in multiple scenarios of VHD mount and unmount failure.
    Here are more details -

    WMI Out of memory (Fixed with UR7 for DPM 2016 and already part of DPM 2019 RTM):
    One of the top scenario where we observed the 40002 error is due to WMI out of memory. In a scenario, where you see 40002 error in DPM Console and at the same time you may see WMI-Activity error event ID 5858 logged with Result code 0×80041006. This code translates to “not enough memory for the operation’. To address this issue, with DPM 2016 UR 7 we increased the default WMI memory limit from 20MB to 60MB by adding registry keys (details below). This change is already part of DPM 2019 RTM.

    If you still see the same failure, the work around could be to increase this limit a bit…

    Still having this issue as of March 23, 2021. Microsoft seems to not be able to get this one solved. I have a few customers already migrating to another backup solutions, after many months of waiting and restarting DPM servers EVERY SINGLE DAY.
