Проверяйте "доменные политики" - возможно, они меняют свойства аккаунтов, от имени которых выполняются SOC и SOM.
https://geonet.esri.com/message/20881?q=0x8000401a"Are you folks using accounts that get touched periodically? Like, overnight, due to some internal IT policy or procedure?
If username/passwords get reset for any reason, even reset back to the same credentials, sometimes this causes problems and the SOM/SOC stack needs to be restarted (no machine reboot should be necessary).
If your organization routinely changes domain accounts, if used, then this will continue to be a problem for you."
