Hi, hopefully someone has overcome this issue already. I received the Windows 10 upgrade and things worked fine - including copying files to my NAS. However I decided to do a clean install on a new SSD drive and when logged into that Windows 10 I cannot copy files to my NAS. Now I know it's not the NAS - I can log back into the old upgraded Win10 instance and everything works (so physically the same PC accessing the same NAS with the same credentials). However I continuously get the "Destination Folder Access Denied" & "You need permission to perform this action" error when attempting to copy in the fresh/clean install of W10.

Any suggestions?
