Upgraded to new computer with win 11 on my network. Now can't access other pc's.

Question

Sorry, I've searched through for the answer to this and tried everything I could find. I have a small home network with a win 10 server with a couple laptops (one a win 10 and one a win 11) and a desktop(was 10 but replaced to 11). Everything was working fine. This morning, I replaced the desktop with a new, windows 11 desktop. I can see the other computer. Ping them, but when I try to access them I get the "windows cannot access.//..." I have gone the other way and can access the new desktop from the other computers.

So, something is keeping me from getting to the shared drives. But, I'm now at a loss. Any help would be appreciated.

Answer 1

Hello,

If your system is windows 11 24H2 version I suspect the problem may be caused by SMB signature. I recommend that you open PowerShell as an administrator and run the following command to disable SMB signing and restart your computer to see if you can fix the problem:

Set-SmbClientConfiguration -RequireSecuritySignature $false

I have seen this post the fix is

But on one of my win 11 PC this did not help until I network reset
