ERROR_INVALID_SERVICENAME - 1213 (0x4BD)

Technical Background

The ERROR_INVALID_SERVICENAME error code is a specific return value from the Windows API, indicating that an operation related to service management encountered an invalid service name. This error typically occurs when attempting to interact with services through functions such as StartService, ControlService, or QueryServiceStatusEx, among others.

Error Details

The numeric code for this error is 1213, and its hexadecimal representation is 0x4BD. The short description provided is: 'The format of the specified service name is invalid.' This implies that the service name passed to a relevant API function does not conform to expected naming conventions or formats.

Common Causes

• Invalid Parameter Values: The service name provided may contain characters or formatting that are not allowed by the Windows Service Control Manager (SCM).
• Incorrect Object Type: The operation being performed is intended for services, but a different type of object was specified, such as a file path or directory.
• Exceeding Limits: There might be a limit on the length or format of service names that has been exceeded.

Real-World Context

This error can occur in various scenarios where service management operations are performed. For example, when attempting to start, stop, or query the status of a service using command-line tools like sc or through programming interfaces such as C++ or PowerShell scripts.

Is This Error Critical?

The criticality of this error depends on the specific operation being performed and the state of the system. If the operation is non-critical, such as a background task, the impact may be minimal. However, if it involves essential services that are required for system functionality, the issue should be addressed promptly.

How to Diagnose

To diagnose this error, follow these steps:

1. Review Operation Context: Ensure that the operation is being performed in an appropriate context where service management functions can be used.
2. Validate Parameters: Check the format and content of the service name passed to the function. Ensure it adheres to the naming conventions for services on Windows systems.
3. Confirm Object Types: Verify that the object type specified matches the expected type (i.e., a service, not a file or directory).
4. Verify Input Data: Validate any additional parameters required by the specific API function being used.
5. Check Limits or Constraints: Ensure that the length and format of the service name do not exceed system-defined limits.

How to Resolve

To resolve this error, consider these practical steps:

• Correct Parameter Usage: Use a valid service name as defined by Windows naming conventions.
• Adjust Operation Context: Ensure that the operation is being performed in an environment where it can successfully interact with services.
• Restore Data: If data corruption or invalidation is suspected, restore the correct service name and retry the operation.

Developer Notes

When developing applications that manage system services, ensure robust validation of input parameters. Use appropriate error handling to gracefully handle ERROR_INVALID_SERVICENAME and provide meaningful feedback to users or other components in your application.

Related Errors

• ERROR_SERVICE_DOES_NOT_EXIST: The specified service does not exist on the local computer.
• ERROR_ACCESS_DENIED: The requested operation requires higher privileges than are held by the user.
• ERROR_INVALID_NAME: A component of the specified path is invalid.
