We want to use the Windows Push Notification Services (WNS) enables third-party developers to raw updates our devices from our own cloud service, but we found an error when we registered for the WNS service. our device system version is [Microsoft WIndows 10.0.14393 LTSB]
The event viewer reported the following error:​

"MDM configuration manager command failure status"?

Okay, it is definitely that command failure status error. Was browsing videos on Youtube, and Discord wasn't even open. Within two minutes of playing two different videos, I had to refresh the page for each one because they were extremely loud.

As soon as I heard it, I recognized it, I went into Event Viewer, and there were the two MDM errors, like I had expected. What is this "family safety group"? I read about it and was told it has to do with microsoft office or something?

EDIT:

Here's another recent post I made. Apparently it is Razer's side to blame:

No Updates for LTSB since 1-15


it looks like you are using Win10 LTSB 2016 (v1607) as Windows Update is listing some updates to the 1607 LTSB release.

the previous LTSB release was the 2015 version (the v1507 or RTM release of Win10 LTSB)

 

"MDM configuration manager command failure status"?

Okay, I just discovered another thing.

Totally unrelated, sometimes I open task manager to view things and end programs.

Yesterday, for about half a second, I saw a program called 'family safety monitor' show up on the task manager list then disappear quickly. After I saw that I rushed to the event viewer and found the same error i've been talking about.
