Microsoft SCMDM: Troubleshooting "Remote Wipe Now."

"A key security feature of SCMDM is the ability to wipe a device remotely. Often time is of the essence, so it is important to know if a wipe was successful or not. Here we will discuss how remote wipe works and how to troubleshoot it...

• An administrator or user submits a wipe request through the console, MDM Shell, or Self Service Portal.
• The wipe request is stored in the DM Engine database for the device to pick up at its next scheduled OMA session... If we were to stop at this point it would be a 'Wipe Soon' and the device would connect at its regular interval (4 hours, for example) and pick up the wipe. Wipes submitted are always submitted as a 'Wipe Now' now command, and thus we have to go a step further.
• In parallel to adding the wipe request for retrieval, the wipe driver also calls the Alerter component to inform the device of a pending wipe request."

[interesting takeaways: there is a Self Service Portal offering, devices are connecting to the Microsoft server on a regular interval, an alerter is required so that wipe happens now rather than soon]
