We have the problem that when we delete clients from Kaspersky Security Center 13.1, no matter by using delete or remove from group/remove from database in unassigend devices they reappear after approx. 1 day. After deletion, the client is not found in unassigned devices nor in the device discovery. Also, the clients have been deleted from Active directory a long time ago and cannot be synced from there as well, domains and IP range poll is deactivated. What we noticed is that in KSC 13.1 the client is not found in unassigned devices after deletion like in version 12 where it had to be deleted a second time to be removed entirely. Anybody else experiencing the same issue?
