Good day. About a week ago we encountered a problem with our ESET Endpoint Antivirus 6.5. We have a server with ERA 6.5 and about 300 various computers with EA 6.5. Everything was OK, but on last week some clients (about 5 so far) running Windows 8.1 Enterprise have Endpoint Antivirus deactivated after restart. Maybe some Windows Update caused this situation? I tried to run the Activate client task on these clients, but without success. Currently we are solving this problem by reinstalling the ESET EA.
