Error 0x80004002 after updating Windows to 1903 ???

[ksor1]

I have this problem in two variations:

1) Allready set up machines have the NASdrive already connected and it works fine !

2) I have a Lenovo W520 where I just installed Windows 10 1903 from scratch and here I CAN'T connect the NAS-drive as a network drive - I have nothing to choose when I try. The Raidar 6,5 finds the drive nicely !

I both cases I have this ReadyNAS Duo icon in the Network folder, but I get this Error 0x80004002 if I double-click and I think I used to get to the administrators logIn dialog.

How to cure this problem ?

The two versions of the Duo  - the v1 sparc (4.1.x firmware) and the v2 arm (5.3.x firmware) are both old products that only support the SMB 1 protocol.  Microsoft is deprecating SMB 1 (the current version is SMB 3), and no longer installs the SMB 1 client by default. 

You can install it manually on the PC - there is a guide here on how to do that: https://infusionsoftware.zendesk.com/hc/en-us/articles/360000193095-SMB1-on-Windows-10-Build-1803

Another option would be to get a new NAS, and perhaps use the Duo as a backup.  The RN212 is the current entry-level NAS and it supports SMB 3.
