Problem in network Windows 11 24h2

In reply to JethroAG's post on December 27, 2024 In this thread, one person suggested to disable IPv6 on their computer's networking configuration. Did you try that?

To address both solutions at once. I did disable IPv6 and verified NIC was showing proper settings for DNS and IP's allocation. Up to statically assigning the address and DNS servers with no change in the problem.

Yes, this works—a direct and simple solution. Just read and follow along.

I have had the same issue as many have mentioned. Updated to 24H2 and bang my network sharing no longer functions. I am running a private network with shared access to Everyone connected to my network. I use this network as a backup solution between my house and my computer repair shop. Hopefully EVERYONE that is having problems with 24H2 killing their home network sharing will read this fix. This worked for me on all 3 of my networked computers. Two of my computers are running Windows 11 Pro 24H2 and one is running Windows 11 Home 24H2. Perform the following steps:

1.   In the seach box immediately to the right of the Start button type gpedit.msc, you will see the Microsoft Common Console Document; click that:

1. In the left pane under Local Computer Policy, navigate to Computer Configuration\Administrative Templates\Network\Lanman Workstation.
2. Open Enable insecure guest logons, select Enabled, then select OK.
3. Restarting computers on the network is likely not necessary, but I did so just as a Nyaaaaa because by this time I was aggravated. This immediately made my networked computers visible and accessible. I didn't have issues with WiFi connectivity only the loss of my network sharing visibility and access. I hope this helps!
