Windows 10: Cannot mount NAS in windows 10 explorer

I seem to have boiled it down to only this error now: the local security authority contains an internal inconsistency

 

I was having the same problem as you, but was not using a password. I read somewhere that Windows 10 would restrict access to NAS if it deemed that the PC was itself insecure. I ended up creating a password (not an account) and I was able to access my NAS. Once I deleted the password to share files remained on and fully accessible. Go figure.

 

What on Earth is going on? I've just managed to map it.

For anyone else experiencing this problem, it was solved after rebooting the NAS drive. I believe that some of my users and shares on my NAS went a little crazy so I deleted, re-added and re-booted. Just took me a day to realise I should re-boot it (although I did this just the other day)!

Thanks all for your input anyways. I hope this lasts!

I should also add, the mount was successful using the following net use command, it still doesn't show up in the map network hard drive wizard:

net use z: \\Path\to\share\folder /user:USERNAME

 

Try forcing Windows to negotiate using legacy SMB 1.0. It corrected some issues I had with accessing QNAP NAS. To do this, type "gpedit.msc" (without quotes") in search, right click on the gpedit.msc search result and select Run As Administrator. Under Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options. Look for Network Security:LAN Manager Authentication Level. Double click on it and select "Send LM & NTLM - use NTLMv2 session security if negotiated" in the dropdown box. Exit gpedit.msc, reboot the computer to implement the policy and then try your NAs again.

 

Thanks sciencegeek for the response, but all is running now. I don't have a lot of confidence so I will try that if this problem reoccurs.

 

Just a guess, did you run the net use from an administrator command prompt? I've noticed that if you do you don't see them in file explorer but you can access them through cd z: (or whatever the letter you assigned is) in command prompt.

 

Hi, no as a regular user, not admin. The drive shows in Windows Explorer, it's just you have to enter it manually, Windows won't list the nas drive in the map network drive wizard.

 

Ah, well, I don't know then I'm afraid.

 

I was looking for another solution and saw this one. Just giving my feedback here. Talked with Synology about a year ago on something very similar here.

It appears you cannot map another shared file from the NAS using a "different" NAS account ---- if ---- you already have something mapped to the NAS on the same PC. That is, apparently, you would need to use the same user account / pass to map any and all shared NAS folders to your Windows File Explorer.

Not very sound as I told them, and it really needs to be an "enhancement" change to the NAS OS to permit mapping from a single PC using different credentials.
