Igen.
Nekem fagyogatott a NAS, es leveleztem a support-al:
I would advise that you do a DSM re-installation. I have provided the directions for performing a re-installation below. Keep in mind your operating system partition and data partition are separate so your data should remain untouched. Also performing a DSM reset will reset your network/package configurations back to default as well as change the default admin user account password to blank.
Also please be aware you can backup the DSM configuration by navigating to "DSM> Control Panel> Update & Restore> Configuration Backup". This will backup User, Group, Shared Folder, Workgroup, Domain, LDAP, Windows File Service, Mac File Service, NFS, FTP, Network Backup, WebDAV, Web Services, SNMP, User Home, Password Settings, Task Scheduler and Disk Usage Report settings.
