Network error update 24H2

Question

Access code in WPF C# Created with Visual Studio 2022

string @strPath = @"\ 192.168.0.xxx \share";

bool boo_lavailable = md_0_3_folder_file_actions.is_folder_available (@strPath, @"No");

Module => is_folder_available (string @strPath, string @strCreate)

Switch (directory.exists (@strPath.trim ()))

{

 case false:

      bool_available = false;

      break;

  default:

         if (@strCreate == @"yes")

        {

            Directory.createdirectory (@strPath..trim ());

            Thread.sleep (1000);

            Switch (directory.exists (@strPath.trim ()))

            {

                case false:

                      bool_available = false;

                      break;

               default:

               bool_available = True;

               break;

           }

      }

      break;

}

Return under 23h2 => bool_available True

Return under 24h2 => bool_available False

Works below 23h2, not under 24h2 (notification no access).

Hello,

 

Thank you for posting in Q&A forum.

This issue could be caused by changes in the network settings or security updates. To further troubleshoot this issue, please kindly try below steps:

1.Check if there's any SMB signing and guest fallback settings change on Win11 24H2

2.Check if SMB signing is enabled on your network and guest fallback is disabled.

3.Make sure the network drivers are up to date.

4.Check if the firewall and antivirus are blokcing the network connectivity.

 

I hope the information above is helpful.

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

 

Best regards，

Jill Zhou
