Removing a device from CCS fails when following the standard procedure listed here:
When a device is decommissioned or you move management of a device to another host, you need to remove the device configuration from CommandCentral. If CommandCentral cannot discover a device, it marks the device as missing. After seven days, CommandCentral deletes missing devices from the database, unless another explorer discovers the device.

2. In the CommandCentral Console, click Settings > Devices.
3. In the Configured Devices table, heck the device whose configuration you want to edit.
4. In the drop-down list, click Remove Device Configuration. Then, click Go.
5. In the Remove Device Configuration dialog box, click OK.
6. In the Task Submitted dialog box, click Yes to see if CommandCentral can remove the device configuration.
