Every now and then the connected smart clients disconnects and all camersa will go blank. while checking the eventlogs in management server i got the following error: Error validating credentials: domain\username. with error: VMO61008. Yo dont have sufficient permissions to complete the operation. But if we wait for say 10 - 20 mins it will automatically resume. We checked the network logs and there is no network interruption. at the same time a basic user is able to login in smartclient. seems to be affecting only the domain users.
