Known issues in this security update

  • Known issue 1

    Symptoms

    Consider the following scenario:

    • You try to access a file server by using the SMBv1 protocol through an application such as File Explorer.

    • The application uses the CONNECT_INTERACTIVE flag for the WNetAddConnection API.

    • You're using a computer that's logged in through Microsoft Account credentials.

    • The network credentials you're using to access the file server share are not present in Credential Manager.

    • The firewall profile on the computer is set to Public.

    To work around this problem, use any of these options:

    • Option 1: If possible, use SMBv2 instead of SMBv1.

    • Option 2: Pass credentials explicitly through the following net use cmd:

      net use \\<serverName>\<shareName> /user: <DomainName\UserName> <Password>

    • Option 3: Change the network profile to Private for private home networks instead of Public.

    • Option 4: Save credentials for trusted network shares in Credential Manager.
