Cannot view/access Diskstation Shared Folders from Win10

Unread post by JackElliott » Thu May 17, 2018 12:26 am

This worked a few months ago (been out of the country for six months). I was able to view and access the shared folders on my Diskstation from my Win10 laptop, no problem.

Now, a few months (and a few hundred megabytes of Windows 10 updates from Microsoft) later, I can't get into any of Diskstation's shared folders in File Explorer.

I can ping the box, and I can connect to the webgui at :5000, so it's online. "Diskstation" shows up in the Network section of File Explorer, but clicking on it, or trying to go to \\192.168.0.xxx\sharedfoldername in File Explorer's address bar just gives me some useless "Windows cannot access \\Diskstation" error.

Synology Assistant can see the Diskstation, but if I try to map a drive to it, I get a "Authentication Failed, Error 58" message. I've tried the auth creds for the Win10 machine I'm trying to connect from, and a couple creds that Diskstation knows about, like the sys admin creds, to the same end.

I expect this has been asked and answered before, I can't imagine I am the first to be dealing with this. And I bet this is due to some stupid decision on Microsoft's part. Just point me to where it's been solved, and my heartfelt thanks for your time!

Update: My wife just got her new laptop, also a Dell XPS running Win10 Home. Same issue as mine. Both are joined to the same Workgroup as the Diskstation, both have SMB 1.0/CIFS File Sharing Support turned on. The Diskstation shows as a device in File Explorer, but none of its shared folders are visible.

Update the 2nd: I also confirm that a third computer on the Workgroup, an older Dell Latitude running Windows 7 Enterprise, has the same behavior: it can ping the Diskstation, browse to its webgui over the local network, and the device is visible in File Explorer, but just like the two Win10 Home computers, cannot view the DS's shared folders nor connect to them by putting "\\192.168.0.xxx\sharedfoldername" into File Explorer's address bar. I just get the "Windows cannot access \\Diskstation" error. So this is not a Windows 10 issue, but something going on with the DS. Anyone feel like helping me sort this out? Without being able to access shared folder, the Diskstation is just a rather large but useless box with blinky-lights.

And finally, here is a portion of smb.conf on the Diskstation. I don't see the problem:

Code: Select all

[global]
        workgroup=MyWorkgroup
        local master=no
        realm=*
        printing=cups
        winbind enum groups=yes
        passdb backend=smbpasswd
        security=user
        printcap name=cups
        load printers=yes
        winbind enum users=yes
[a_shared_folder_name]
        invalid users=nobody,@management,filestation,nobody
        valid users=jacquie,admin,jack
        comment="System default shared folder"
        path=/volume1/web
        guest ok=yes
        browseable=yes
        fileindex=no
        mediaindex=no

        read list=nobody,jacquie,nobody
        write list=nobody,admin,guest,jack,Xack Elliott,nobody
        writeable=yes

I would do:
make a 4seconds reset of the DS to reset all network settings to default (data will be safe).
Use the synology assistent to re-establish the connection
First try it with a router assigned dynamic IP to see if this works.
Later set the IP adress to fixed. Set it and just a few IP numbers HIGHER than the router IP, whatever IP is free, and make this a reservation in the router.
Enable SMB2/3 and disable SMB1 as SMB1 is not safe.

this should work...
Please share if a reply was useful or how the issue was solved, it helps other DS users.

Thank you.

4-second reset turned off DS. Restarted with a second press of the button.
Use the synology assistent to re-establish the connection
Synology Assistant sees the DS. But if I try to map a drive, it gives "Error: Authentication Failed (ErrorCode:58)"
First try it with a router assigned dynamic IP to see if this works.
It doesn't. DHCP assigns an IP to the DS, that's where DSAssistant finds it. Windows File Explorer shows the device in the "Network" section, clicking on it opens the webgui at :5000, but File Explorer shows none of the shared folders shown

I had the same problem after Windows 10 1803 update, it's two days I am working to find a comfortable solution, perfection still not found...

To access DS shared folder I edit hosts file (C:\Windows\system32\drivers\etc) and put 192.168.xxx.xxx <name of ds>

Now I disable SMB 1 on Disk Station (min SMB2, max SMB3), but to see the DS in File Explorer I must leave SMB1 on on the Windows 10 Pro pc's, while on another Win7 Pro pc I disabled SMB2 and still work.

IMPORTANT: My two Windows 10 PC have SMB1 enabled by default! I don't care of this setting before, so I see this behaviour only after windows update to 1803, so I don't know how was before.

Mine unsolved problem is that if I power on first the Win7 pc I can see DS and other PC's in File Explorer (SMB1 disabled or enabled on the PC), but if I power first the Windows 10 Pro PC the situation is reversed.

Enabling Local Master Browser in DS don't help (and I prefer to do not use it since it disable HDD power management).
Force one PC to be the LMB don't help.

Thank you.

I already have the DS in the hosts file.
Now I disable SMB 1 on Disk Station (min SMB2, max SMB3),
How? I am running DSM 4.2-3259 and do not see a way to change SMB settings. Control Panel > Win/Mac/NFS does not have any options for SMB.

Whad DS do you have? I have two DS with latest OS 6.1.6, may be your is too old and implement only SMB1.

My first solution was to set DS to use only SMB1 (6.1.6 have that option), doing so SMB2 and 3 whent disabled on DS, and there was the only way to avoid error on connection in the Win10 PC, but I don't remember how pc's works togheter with this setting.
I remember only that in this case edit the hosts files was unnecessary.

Now I write from the 2nd win10 pc, it act like the other one: in network explorer I don't see the two DS, while I see only the Win7 pc (???).
I edited the hosts file.
I mapped some drives (ex. M: -> \\DS\music) first using Synology Assistant, but when I restar Windows the appear with red cross on them, so I must click on it to activate the mapping.
I mapped them using File Explorer -> Computer (menu) -> Connect lan unit and giving the IP of the DS as path (ex 192.168.1.100\music), DS\Music don't work.

My DS is pretty old: model 209j

Maybe Windows 10 has changed things to make accessing DS folder shares not possible, but why can I not access the shares from a Win7 Enterprise machine?

My 211+ is very slow with 6.x.x OS, I plan to migrate files to the new one.

Few minutes I made another test...

Meanwhile, you tried to put these lines in Win 7 registry?:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Browser\Parameters]
"MaintainServerList"="Yes"
"IsDomainMaster "="1"

Really frustrating...

I tryed to keep off the Win7 pc and work with the two win10 pc's.

I have this situation:

Win7 Pro pc with SMB1 OFF
Win10 Pro pc with SMB1 Client/Server ON, SMB2-3? ON
Win10 Pro pc with SMB1 Client/Server ON, SMB2-3? ON

Result: The first PC I power on (win7 or win10) see all PC's and DS on the same Group in the LAN, the second one (win7 or win10) NOT.

I made the change of "MaintainServerList"="Yes" and "IsDomainMaster "="1" only in win7 pc (in this test the PC was power off).


The Win10 pc's must have SMB1 turned on, while the Win7 one not!

See your DS model have DSM 4.2 maximum but updated on 2017, so I don't know if it is settable to SMB2-3, may be there is a infra-release update, refer to this guide to set it (if it help):

https://www.synology.com/en-us/knowledg ... macnfs_win

This morning I found a solution if it does not change nex days...

I disabled SMB1 on all the PC's and the two DS. Rest registry keys aboud 'Browser' service to default value. Take for the moment the 'hosts' file entries.

Win 10 PC's won't see the other PC's in File Explorer (except the Windows 7Pro pc seen from one of them...???), but I can manually create link, or map drive letters to DS shared folders, simply typing \\<DS name>\<folder name>.

Win 7 PC still see all the others in File Explorer despite it has SMB1 disabled...!?

Thank you, but this is going nowhere for me. I don't have your version of DSM and it doesn't look like you have a solid, dependable solution for yourself yet.

Synology: Why isn't this fixed? I have a DS that is little more than a brick with lights. Completely useless.

A couple of observations:

In his post at 8:39am yesterday, eaz suggested:

"I would do: make a 4seconds reset of the DS to reset all network settings to default (data will be safe)."

You responded that you tried that, and it turned off the machine. That's because you pressed the wrong button. You don't do this by pressing the on/off button on the front of the machine, you do this by using a paperclip to press the reset button recessed in the back of the machine. So, try that (I think it will also reset your admin password to the default), and see if it's as simple as a reset on the machine. This will not endanger your data in any way.

If that doesn't work:
I don't remember DSM4.2 very well, but I suspect that it doesn't do SMB2 or above, and is confined to SMB1. SMB1 is turned off by default in the current update of Windows 10. But you can turn it on. In the Cortana window in the lower left corner of the screen on your Windows 10 machine, enter "Turn Windows Features On or off", and then go to the Windows Features selector that pops up. Check the box for "SMB 1.0/CIFS File Sharing Support," hit OK, and reboot the Windows machine.

Possibly, doing either or both of those will solve your problem here.
