Connecting to NAS - "Windows cannot access"

You have SMB 1 enabled on the NAS just as I thought. Change your Minimum SMB setting to SMB2 and the Maximum setting to SMB3. Restart your computer afterwards and see if things have improved for you.

Unfortunately, I did say in my comments already, those settings did not help.

Please restart your Computer so that your network is re-initialized to enforce the changes you made.

Thanks but I restarted both my PC and the NAS already and still get the same error.

Unfortunately your error is a generic code that does not give anything meaningful. I myself experienced similar problems after the last Win 10 upgrade but without the 0x80004005 error. Removing SMB 1, NetBIOS, and Wins server from the network resolved the issue for me. Sorry it did not work for you.

Hi there
If your NAS is a Linux type OS there should be a samba.conf file (samba config) usually under root directory /etc/samba

On the box ensure you are a samba user -- as root type smbpasswd -a user where the system will prompt you to enter a password and then will add you to the smb users list.

Now ensure in the [global] section you enter max protocol = NT1 (it's changed in Samba V4 from SMB1 to NT1) and ensure SMB1 is enabled on Windows.

On the NAS box restart samba (usually 2 services smb and nmb need to be restarted -- if you are uncomfortable with the commands just re-boot the box). Services might be called smbd and nmbd depending on the Linux OS.

Now as root (su or sudo) type testparm - that will check the samba files are OK

now type (again as root) systemctl nmb status -l that will show you if samba is running correctly and ready to serve connmections (or nmbd if that's the service name on your OS).

On the file manager check network / shares and you should see shared directories

Windows should also now see the shares as well -- if not get the IP address if your NAS box (on Linux type ifconfig - not ipconfig as windows) and note the ip address -- now in windows file explorer access via the ip adress and see if your shares are available.

Never did think the issue had anything to do with SMB settings. I've got a Western Digital PR4100 Pro and I never needed to change any SMB settings. In fact mine defaulted to SMB 3


One thing Jim said that I would do is reboot the NAS box to see if that clears things. And the reason why I say it's not a Windows issue is because the OP stated the box works with his other Windows machines.

BTW I'm running the latest version of Windows 10 Pro x64 (1809)
