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

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

I got gpedit to go.
a couple of things were already deselected. I did the rest and rebooted, but still nothing.

I'm giving up
Nice of MS to clobber the home user in pursuit of the bad hats.
My PCs sit behind a router with Firewall, have the W11 Firewall enabled, along with a RT AV. I don't use pirate software, and avoid nasty sites.
I thought that was safe.
Apparently not enough for MS.
So, a small 2 x disc Netgear NAS, a WD network disk will be heading for landfill, along with the 4 x disk Netgear NAS if this keeps up !

Thanks to everyone for trying to help

Ugh.. I hate to pile on here, but I'm having a very similar issue.

I have a POS system, DOS based, that runs SMB1.0.. At some point recently.. No more access to it via Win11. Win10 still works great. I've tried, I think all of the suggestions here.. No love.

I have wiresharked it.. I can share that capture if you like.. But I think the event viewer logs might be more useful.

First off, if I try to connect via command prompt.. That results in

Code:

C:\Users\NCCTest>net use Z: \\192.168.0.65\posfiles
System error 67 has occurred.

The network name cannot be found.

Now.. That is there. That command works perfectly on a Win10 machine

Code:

C:\Users\NCCTest>net use Z: \\192.168.0.65\posfiles
The password is invalid for \\192.168.0.65\posfiles.

Enter the user name for '192.168.0.65':

Now.. On win11.. When I do that, if I go into event viewer->Appllications and Services Logs->Microsoft->Windows->SMB Client->Connectivity.. i get 2 errors and an 'informational'..

In this order..

Information -
Could not find a certificate mapping that matches the server name.

Connection type: Quic
Server name: 192.168.0.65.

Error -
Failed to establish a network connection.

Error: The transport connection attempt was refused by the remote system.

Server name: 192.168.0.65
Server address: 192.168.0.65:445
Instance name: \Device\LanmanRedirector
Connection type: TCPIP
Port origin: The port was selected from the global registry settings.

Guidance:
This indicates a problem with the underlying network or transport, such as with TCP/IP or QUIC/UDP, and not with SMB. A firewall that blocks the TCP or UDP port listed in the Server Address field can also cause this issue.


Error 2 -
Failed to establish a network connection.

Error: The QUIC connection was idle.

Server name: 192.168.0.65
Server address: 192.168.0.65:443
Instance name: \Device\LanmanRedirector
Connection type: Quic
Port origin: The port was selected from the global registry settings.
Connection ID: 0x6BB029B26C91FE44
Client certificate thumbprint: 0x0000000000000000000000000000000000000000

Guidance:
This indicates a problem with the underlying network or transport, such as with TCP/IP or QUIC/UDP, and not with SMB. A firewall that blocks the TCP or UDP port listed in the Server Address field can also cause this issue.




I've disabled the signing and QUIC, or so I think.. But the errors seem to suggest.. They're still enabled.

Signing.. Is certainly off

Code:

PS C:\Users\NCCTest> Get-SmbClientConfiguration | FL RequireSecuritySignature


RequireSecuritySignature : False

I've also run from powershell

Code:

 Set-SmbServerConfiguration -EnableSMBQUIC $false

Struggling here a bit.. Just fishing for ideas. Obviously.. Yes, I have SMB Client enabled on both sides.


just in case it helps.. results of Get-SmbClientConfiguration from both machines..
