If this is the same issue we faced:I think there was an openssl patch for the NetAgent, and for the groups that we have configured Automatic Installation it automatically reinstalled NetAgent with the patch. For some reason, whenever NetAgent is updated (since version 13) KES SC is considering it a new device and marking the old one as unmanaged, then we have to again move from Unassigned devices to the correct group. I hope Kaspersky solved this issue, we cannot afford to do this after each update. This is also creating issue with licenses considering each PC is using two licenses now until we delete the old device entry, totally frustrating.
