Windows 11 update 24H2 changes network access

Thank you for posting in Microsoft Community forum.

Based on your description, here are some possible solutions to help you fix the tethering problem and find the settings accordingly.

1. Check the Network & Sharing Center settings:

Open "Settings" -> "Network & Internet" -> "Advanced Network Settings" -> "Network & Sharing Center" and click "Change Advanced Sharing Settings". Make sure that both the "Enable Network Discovery" and "Enable File and Printer Sharing" options are enabled.

2. Check the network profile type:

Open "Settings" -> "Network & Internet" -> "Ethernet" or "Wi-Fi". Click the name of the network you are connected to and make sure that the network profile type is set to VPC.

3. Enable SMB 1.0/CIFS file sharing support:

Open Control Panel -> Programs and Features -> Enable or Disable Windows Features. Find and check "SMB 1.0/CIFS File Sharing Support" and click "OK".

4. Make sure the service is activated:

Press the Win + R keys, type services.msc and press Enter.

Ensure that the following service is started and set to automatic: Function Discovery Provider Host

Function Discovery Resource Publication

SSDP Discovery

UPnP Device Host

5. Use Local Security Policy Settings:

Press the Win + R keys, type secpol.msc, and press Enter.

Go to "Local Policies" -> "Security Options".

Ensure that Network Security: LAN Manager Authentication Level is set to Send LM and NTLM Responses.

6. Reset network settings via Command Prompt:

Open a command prompt as an administrator and run the following command:

netsh int ip reset

netsh advfirewall reset

ipconfig /release

ipconfig /renew

ipconfig /flushdns

7. Check and modify shared folder permissions:

Right-click the folder you want to share and select Properties. Go to the "Sharing" tab and click on "Advanced Sharing". Make sure the "Share this folder" option is ticked and grant read or write permission to "Everyone" in "Permissions".

8. Check your firewall settings to make sure File & Printer Sharing is allowed through the firewall.

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

I can confirm access to local network storage, connected through the router and netowrk sharing doesn't work with 24H2. I reinstalled the 23H2 version and it works perfect.

There are many of us that are having this issue.

The first half of your suggestions we have mostly all tried, that 2nd half maybe will have some impact.

What does work at least to let you see the 23h2 network, is that you MUST sign in with a password NOT a Pin. There is still a permission issue that I'm trying to resolve.

It seems that with every new version home networking get more difficult.

This works for me, thx a lot

I tried everything, and I think I finally found the culprit. In Windows Defender Firewall with Advanced Security, 24H2 does two things: (A) disables all File and Printer Sharing rules, and (B) adds a bunch of rules called File and Printer Sharing (Restrictive) [blah blah blah].

In some cases, even if (A) is not done, (B) is done and something else is disabled that breaks file sharing.

The solution is:

1. Go to Windows Defender Firewall with Advanced Security => Inbound Rules
2. Scroll down to File and Printer Sharing. Look at column "Profile" and make sure all rules with your correct Profile are enabled (right click - enable)
3. Enable all items at the bottom which have the word (Restrictive) in the name. The most important one is called File and Printer Sharing (Restrictive) (SMB-In).

To be clear, just enabling File and Printer Sharing (Restrictive) (SMB-In) should do it, but I went overboard to make sure the computer responds to pings, etc.
