I know this topic has arisen many times and I've researched extensively to no avail. Here is my situation:

Computer B runs on Windows 10; computer A is a dual boot system (Windows 10/11)
File sharing works fine when computer A is booted into Windows 10.
However, when computer A is booted into Windows 11, attempts to access shared files on computer B generate a network path not found error message.
Computer B can see and open files shared on computer A.
Computer A can see computer B in file explorer but cannot access shared files on that computer (error code 0x800070035).
Computer A can ping computer B using its IPv4 address and by its name <Computer B>.mynetworksettings.com

Steps taken so far:
1. verified that all network sharing settings are enabled correctly
2. verified that "require password" is disabled
3. enabled SMB1 (I am uncomfortable leaving that enabled)
4. verified that all required services are running:
o Function Discovery Provider Host Running....Manual - changed to Automatic
o Function Discovery Resource Pub Running....Manual (Trigger Start) - changed to Automatic (Trigger Start)
o SSDP Discovery Running....Manual - changed to Automatic
o UPnP Device Host Stopped....Manual - Started and changed to Automatic
5. flushed DNS cache
6. ran nslookup by IPv4 address: correct name returned <Computer B>
7. entered \\<IPv4 address> in file explorer search bar: returned Windows cannot access \\<IPv4 address> error code 0x80004005
8. entered \\<Computer B> in file explorer search bar: returned Windows cannot access \\<Computer B> error code 0x80070035
9. tried using a local account rather than my Microsoft account but that did not work.

It shouldn't be this hard :unsure:

I'm preparing to try Nearby Sharing but I first have to install Bluetooth adapters to these older Dell desktops.
Thanks in advance for any suggestions. In the meantime, my USB flash drives are being put to good use.

Regards,
John

For the Bluetooth [BT] part I have good success with IOGear USB dongles where the Wireless adapter does not include BT.
For file saving and sharing I have a Buffalo NAS attached to my Router and any Wired or Wireless/Wi-Fi attached to the Router can Map a folder on it and files in that folder. I have Win7, Win10 and Win11 Desktops attached via Ethernet cable plus some Wireless Notebooks at various times. I don't use dual-booting.

I got this from Reddit. It fixed the problem for me.

https://www.reddit.com/r/sysadmin/comments/1hnas4d/windows_11_24h2_update_cannot_access_network

Powershell (as admin)

Set-SmbClientConfiguration -RequireSecuritySignature $false -Force

Has resolved various PCs with similar symptoms in the last two weeks. Devices could see the device hosting the share, had file and printer sharing turned on etc. Could see the folder but just couldn't open it. Think the error was 0x80070035 network path not found.

Control SMB signing behavior

Windows 11, version 24H2 Enterprise, Pro, and Education require both outbound and inbound SMB signing.

Guesing this was not the case for 23H2 and prior.

Maybe try these as well if first one doesn't do the trick:

Set-SmbClientConfiguration -EnableInsecureGuestLogons $true -Force

Set-SmbClientConfiguration -RequireSecuritySignature $false -Force

Set-SmbServerConfiguration -RequireSecuritySignature $false -Force

To HTA...I will definitely try this fix 🤞 It makes more sense than some of the other purported remedies.
I am getting that same message you referenced:
Error code: 0x80070035
The network path was not found
