System Error Codes, also known as Windows Error Codes, are numerical values that Windows operating systems and software applications use to represent specific errors or issues encountered during program execution or system operation. These error codes help users and developers identify and troubleshoot problems more efficiently. Here are a few common system error codes and their meanings:
Error Code 5 (ERROR_ACCESS_DENIED):
- Meaning: The requested operation was denied due to insufficient permissions.
- Common Causes: Trying to access or modify a resource without the necessary permissions.
Error Code 404 (ERROR_NOT_FOUND):
- Meaning: The specified file or resource could not be found.
- Common Causes: Typically encountered when a web page or file is missing on a web server or when a file cannot be located on a local system.
Error Code 1202 (ERROR_BAD_PROFILE):
- Meaning: The user profile is corrupted, or the user does not have a profile.
- Common Causes: Issues with user profiles on a Windows system.
Error Code 2 (ERROR_FILE_NOT_FOUND):
- Meaning: The specified file could not be found.
- Common Causes: Similar to ERROR_NOT_FOUND but specifically refers to files.
Error Code 1068 (ERROR_DEPENDENCY_NOT_FOUND):
- Meaning: One of the services on which this service depends does not exist.
- Common Causes: Typically seen when attempting to start or configure Windows services.
Error Code 5 (ERROR_ACCESS_DENIED):
- Meaning: The requested operation was denied due to insufficient permissions.
- Common Causes: Trying to access or modify a resource without the necessary permissions.
Error Code 3 (ERROR_PATH_NOT_FOUND):
- Meaning: The system cannot find the path specified.
- Common Causes: Occurs when a file or directory path provided in an operation is invalid or doesn't exist.
Error Code 87 (ERROR_INVALID_PARAMETER):
- Meaning: The parameter is incorrect.
- Common Causes: Typically encountered when a function or operation is given incorrect or invalid input parameters.
Error Code 6 (ERROR_INVALID_HANDLE):
- Meaning: The handle is invalid.
- Common Causes: Occurs when attempting to use a handle (e.g., file handle or registry key handle) that has become invalid or closed.
Error Code 997 (ERROR_IO_PENDING):
- Meaning: Overlapped I/O operation is in progress.
- Common Causes: This is often seen when asynchronous I/O operations are used, indicating that the operation is still pending and not yet completed.
