Several actions at the ePO console can lead to this problem:
- Running the Duplicate Agent GUID task removes the DE User assignment from the system because the user assignments are mapped to the system and have now been deleted. The task removes both entries of the GUID from the database and re-creates the object at the next agent-server communication interval (ASCI). The action leads to the AutoID being changed within the ePO SQL database.
- Running one of the system queries for duplicate systems or sequence errors by selecting a system, and then clicking Actions, Directory Management, Move GUID to Duplicate List and Delete system.
- Selecting a system from the ePO Tree and clicking Actions, Directory Management, Move GUID to Duplicate List and Delete system.
- Performing any action that deletes a system in ePO, causes the managed system to lose all user assignments.
At the next Agent to ASCI when the client communicates with the server, all previously assigned preboot users are removed from the client, leaving the computer in a locked-out state.
