Can no longer backup Windows 10 PC to ReadyNAS 102

I am using Firmware 6.4.0.  I have not upgraded to 6.5.2 because in the past after I install the upgrade the NAS will hang on reboot.  Then I usually have to call for Tech support so I won't lose any data while trying to fix it.

While it's clear there is some risk when doing a firmware upgrade, a better strategy is to have a backup plan in place.  There are lots of security updates made over the past four years, and other software improvements.

And if you use the NAS for primary storage, you need a backup plan anyway.

Can you access the NAS shares from the PC?

If you can't, then what happens if you run CMD on the PC and enter this:

net use * /delete

net use t: \\nas-ip-address\data /user:admin nas-admin-password

using the real IP address and admin password of course.  If you use flexraid, also change "data" to match your volume name.  Be careful on the typing - particularly slash directions and the spaces.

The first command terminates any open SMB sessions.  If it prompts, let it proceed.  If there are none, it will tell you that.

The second command attempts to mount the NAS data volume as drive letter T.  Let us know if this is successful (and if not, what error you get).

It's possible that your old firmware is using SMB 1 for the backup.  Microsoft is deprecating this version of the protocol.  You could also run "turn windows features on or off", and see if the SMB 1 server is turned on in your PCs.  If it's not, you could enable it, and see if that solves your problem.
