Despite enabling SMB 1.0 CFS W11 won't see my network drive

2pods · Feb 25, 2025

As above really.
I have an old network drive which shows up on on my other systems (both Win10 with SMB 1.0 enabled), but not my Win11 system.
I can see disk the icon in "Network" part of File Explorer, but I can't connect to a share via "Connect Network Drive", as it doesn't show up in the drop down (unlike my other systems).

I did the same thing as I did on the other systems i.e. enabling SMB 1.0/CFS via Windows Features, but it's not happening.
I've tried checking all three sub options, individually only, plus deselecting the "Remove SMB 1.0/CFS if not needed, leaving the other two selected.
I've also rebooted everytime.

Windows 11, version 24H2, OS build 26100.3194, Windows Feature Experience Pack 1000.26100.48.0

If you need SMB 1 to connect to a old drive ensure you only enable the client feature. Enabling server opens your system to attacks and is not necessary.

Also how technical are you? If you can install wireshark and run that, select your network interface in use (will have a line graph next to it indicating activity). Then attempt to connect to the share. Stop the capture and save the npcap file. You can DM me the capture if you don't want to share it publicly here.

Welcome to Eleven Forum @2pods

First, remove the SMB 1.0/CIFS Server, you don't need it and it's an increased security risk. That one is for legacy SMB 1.0 devices (such as Windows XP) to connect to shares on this PC.

You are on Windows 11 24H2. Starting with 24H2 tougher security is enabled by default. Insecure guest connections are not allowed. You can turn this off. More here:

For W11 Home see:
Windows 11 cannot access other computers, but can be accessed by the other computers - post #34
Edit: link corrected

Thanks both.
Wireshark does indeed sound very technical, so I'll keep that as an option for now @neemobeer, thanks.

Thank you Bree.
I was on the old Ten forum, and thought I was on this one, but in the end it was simpler to re-register.
I'll give the links a good read and report back tomorrow, or sooner depending on results

Oops! We ran into some problems.

Has it been deleted, or moved ?
Thanks

It's Ok, I found it.
However, my regedit key is already set, and I have no gped as I'm on W11 Home.
I'll keep trying

What I did to my 2 NAS boxes, oldest is a 2012 model, prior to 24H2 was to disable all Guest users in the NAS boxes and in the Router to which they are connected.
Both NAS have min SMB 2/max SMB 3 enabled, Windows set to SMB 1.0 Auto Removal, i.e. only the first box ticked.

I see all shared folders in both NAS boxes.

My extremely limited understanding of networking is that security requirements have increased.

I see Post #4 has covered the points, I must have seen those before, I forget.

2pods · Feb 25, 2025

Hi
Thanks for your help.

I knew about the extra security, as I had to enable SMB 1.0/CIF on my two W10 boxes a while ago.
So far, nothing has worked (the registry hack was already set, and I don't have gped as I'm on W11 Home)
AFAIK both the wee Netgear NAS and the WD World drive are SMB 1 only.

As this box is just for email etc, it's not crucial.
I have a more recent NAS that shows up, but I did like my old WD World drive and old Netgear NAS for another backup location

My bad, I posted a broken link. I've corrected it now.

All I do with every new 24H2 Install I First Turn on SMB 1.0/CIFS Client and SMB 1.0/CIFS Server
Next go into Group Policy

Computer Configuration, Windows Settings, Local Policies, Security Options
Double click on Microsoft Network Client: Digitally sign communications (always)
Double click on Microsoft Network Client: Digitally sign communications (if server agrees)
Set both of these to "Disabled"
Click on OK.

Computer Configuration, Administrative Templates, Network, Lanman Workstation
Double click on "Enable Insecure Guest Logons"
Set this to "Enabled"
Click on OK.

Works everytime

Unfortunately not applicable in my case, as it's W11 Home.
No group policy editor

For Home open Regedit and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters. Create a new DWORD, name it RequireSecuritySignature and set its value to 0.

Wolfzz · Feb 26, 2025

Make this as a Bat File and run it it will give you access to group policy editor like Win11 Pro in Win11 Home Edition

@echo off
pushd "%~dp0"

dir /b %SystemRoot%\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientExtensions-Package~3*.mum >List.txt
dir /b %SystemRoot%\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientTools-Package~3*.mum >>List.txt

for /f %%i in ('findstr /i . List.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"
pause

@Bree
I'd went to do that very thing last night.
However, it was already set that way.

@Wolfzz
Just run it like an old DOS *.bat file ?

Yes just copy my text into a text doc and then save it to this and run it

gpedit-installer.bat

It came up with :
"
Elevated permissions are required to run DISM.
Use an elevated command prompt to complete these tasks.

Error: 740"

I know enough to have installed the 2 NAS and drive, and setup network drives, but I've never really used bat files since DOS

You need to right-click on the .bat file and 'run as administrator' to be able to use the DISM commands.

I did.
I let it finish, then ran gpedit.msc and got a Windows message saying "can't find gpedit.msc".

I'm sorry for plaguing the forum with all this, but It's always just worked the way I set it up, and a lot of this is a bit beyond me
