Did Modern Standby behavior change in the last few years? PCs in ModS used to stay network connected and would receive MDM commands. Especially awesome were wipes, which would happen even at night, as long as the deivce was in ModS and network connected.

In fact, modern apps could periodically connect and sync as well, such as the old Windows Mail app.

These days, it seems devices always, invariably completely disconnect from the network while sleeping.
