The error code Win32 0x00000557 translates to ERROR_INVALID_LOGON_TYPE, indicating that an attempted login process used an invalid or unsupported login type. Login types define the method used for user authentication during login attempts.

Here’s a breakdown of the error and potential troubleshooting steps:

Understanding the Error:

  • Windows supports various login types, such as password-based login, smart card login, or domain-based authentication.
  • This error arises when a program or login attempt uses a login type that is not recognized or not supported within the system configuration.

Common Causes:

  • Incorrect Login Type Specified: The program or login attempt might be using an outdated or incompatible login type not suitable for the current system setup.
  • Program Bug (Less Likely): In rare cases, a bug in the program handling the login process could lead it to use an invalid login type.
  • Configuration Issues (Less Likely): In complex network environments, domain or security policy configurations might restrict specific login types, leading to this error if an unsupported type is attempted.

Troubleshooting Steps:

Here’s how you can address the ERROR_INVALID_LOGON_TYPE error:

  • Identify the Program (if applicable):

    • If a specific program is involved in the login attempt, determining its identity can help understand the expected login type.
  • Verify Login Type Requirements:

    • Consult program documentation or system requirements to understand the supported login types for the program or system you’re trying to access.
  • Standard Login Methods (if applicable):

    • If unsure about the program’s requirements, try using standard login methods like username and password. These are typically widely supported login types.
  • System Administrator Involvement (Recommended):

    • Involving your system administrator is generally recommended, especially for complex network environments or domain-based login issues. They can analyze system configuration, program behavior, and security policies to determine the appropriate login type for your scenario.
  • Update Program (if applicable):

    • Consider if there are updates available for the program encountering the error. Updates might address bugs related to login type handling.

In Summary:

The Win32 0x00000557 error (ERROR_INVALID_LOGON_TYPE) indicates that an unsupported login type was used during a login attempt. By identifying the program involved, verifying login type requirements, and potentially involving your system administrator, you can ensure the correct login method is used to establish a successful login session.
