Hope you're well.
I'm accessing my network files hosted on a Synology via windows explorer (unc path &/or mapped drive) and since a few days I'm unable to open any file via explorer or any application; I'm getting the following messages:
Open a picture: "it looks like you don't have permission to view this file. Check the permissions and try again.
Open any other file : "The directory name is invalid."
Open with other program than Windows one also mention permission issue.
Diskcleanup, SFC /Scannow (clean), chkdsk /f /r (clean), Delete all network drives & windows credential for this network, killing all tasks, safe boot, disabling WinDefender, Firewall, checking if new ethernet drivers, ccleaner…
I'm using b16251 of W10x64 and had this problem twice with older versions of W10. Only solution I found at the time was to format and reinstall windows as I'm completely handicaped in this situation.
Please note I can access properly all files of that network from other computers using W10 & W7 so it's definitely linked to this setup.
Not sure if it's related to insider preview as I had this problem on Creator Update 1703 and upgraded to preview thinking it will solve the problem…
Can you please help me trace and fix this issue please ? Thanks a lot!
