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

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:

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

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.

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.
