Error Code 0x80040616 Summary
The error code 0x80040616 typically indicates an issue with Active Directory Lightweight Directory Services (AD LDS) or related services on a Windows system. This error can occur when there is an attempt to connect to an AD LDS instance using LDAP, but the connection cannot be established due to various reasons such as incorrect configuration settings, network issues, permissions problems, or service status not being active.
This code specifically translates to a “Logon failure: unknown user name or bad password” error when trying to authenticate against an AD LDS service. It may also appear in other contexts where authentication or connection attempts are made to AD LDS or similar directory services.
To resolve the 0x80040616 error, follow these detailed steps:
1. Verify that the username and password provided for connecting to AD LDS are correct and have appropriate permissions to access the service.
2. Ensure that the Active Directory Lightweight Directory Services instance is running on the target server or workstation by checking through “Services” in the Administrative Tools section of Control Panel.
3. Confirm that network connectivity exists between your local machine and the AD LDS server, including firewall rules allowing LDAP traffic (port 389) to pass through.
4. Review configuration files associated with any client applications attempting to connect to AD LDS for accuracy in specifying server name or IP address, port numbers, and other connection details.
5. Check Event Viewer logs on both the local machine and the AD LDS server for additional error messages that might provide clues about why the connection attempt failed.
6. If changes have been made recently to security policies or user accounts within Active Directory, ensure they did not inadvertently cause the issue by revoking necessary permissions needed for connecting clients.
7. As a troubleshooting step, consider attempting to connect using the same credentials with an LDAP browser tool or similar diagnostic utility to isolate whether the problem lies with application code logic or AD LDS itself.
Where Does Error Code 0x80040616 Appear? Description
The error 0x80040616 generally occurs in scenarios where software applications rely on connecting to Active Directory Lightweight Directory Services (AD LDS) as part of their operations. Common contexts include:
– Authentication failures when an application attempts to authenticate users against AD LDS for access control purposes.
– Connection issues when a client application tries to query user data or other directory information stored in AD LDS but encounters configuration discrepancies, network restrictions, or service unavailability.
– Integration problems with systems that depend on AD LDS for synchronization tasks involving user accounts, groups, and permissions across different platforms.
This type of error can also surface during development stages when testing new applications against existing directory services environments, highlighting potential setup issues before full deployment.
Howto solve error code 0x80040616
To resolve the 0x80040616 error, follow these detailed steps:
1. Verify that the username and password provided for connecting to AD LDS are correct and have appropriate permissions to access the service.
