NETGEAR RN10200 NAS Firmware 6.1.5

Fixes:
- Improved Active Directory handling of slow/remote connections by adding an option to force authentication each time. The "Not sync ADS accounts to local DB" option should be used when each authentication is validated with the ADS server.
- Fixed system instability issue with Photos II image import.
- Fixed ReadyNAS 4220 power supply unit alarm.
- Compatibility improvements for Windows 8.1 Internet Explorer 11.
- Fixed smart snapshot automated data pruning issue which could cause devices to not shutdown properly.
- Fixed anti-virus engine to address out of memory error and issue preventing successful Windows backup.
- FTP permissions update. When new files or sub-folders are created over FTP, file or sub-folder permissions are set to the same settings as the share-folder permission.
- Fixed drag and drop file compatibility with Chrome.
- SMB security patches applied.
- Kernel patches applied.
- Improved performance with large volumes (Most likely seen on the ReadyNAS 104). A factory default is required to make the changes. Copy all data off the ReadyNAS, upgrade the firmware, factory default the unit, and copy all data back onto the device
