The error code Win32 0x0000055F translates to ERROR_TOKEN_ALREADY_IN_USE, indicating that a security token you’re trying to use is already in use by another process. Security tokens are objects in Windows that represent a user’s security context, including their privileges and access rights.

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

Understanding the Error:

• Security tokens are essential for controlling access to system resources.
• This error arises when a program or process attempts to use a security token, but that token is already being used by another process. This can happen due to various reasons.

Common Causes:

• Multiple Login Attempts: You might have accidentally initiated multiple login attempts, and both attempts are trying to use the same security token.
• Long-Running Process: A program might be holding onto a security token for an extended period, preventing other processes from using it.
• Incorrect Token Usage (Less Likely): In rare cases, a programming error might lead to a program requesting or using a security token incorrectly, causing conflicts.

Troubleshooting Steps:

Here’s how you can address the ERROR_TOKEN_ALREADY_IN_USE error:

• Identify Conflicting Process (if applicable):

  • If possible, try to identify the process that might be already using the security token. Tools like task manager (with certain views enabled) can provide insights into running processes.

• End Conflicting Process (if applicable):

  • If you can identify a long-running process that might be holding onto the token unnecessarily, you can carefully consider ending that process (if safe to do so) to release the token.

• Log Off and Log On Again:

  • Logging off and logging back in can terminate any lingering processes or attempts that might be using the security token, allowing you to re-establish a fresh security context.

• Restart the Computer:

  • Rebooting the computer clears out temporary system states and terminates all running processes. This can often resolve the issue if a temporary glitch was preventing the token release.

• System Administrator Involvement (Recommended – for complex scenarios):

  • If the error persists or you’re unsure about the conflicting process, involving your system administrator is recommended. They can analyze system logs, process information, and security tokens to diagnose the root cause and take appropriate actions.

Security Note:

• Security tokens hold significant access rights. Be cautious about ending processes or modifying system configurations without understanding the potential consequences.

In Summary:

The Win32 0x0000055F error (ERROR_TOKEN_ALREADY_IN_USE) indicates that a security token is already in use. By identifying conflicting processes, restarting the system, or consulting your system administrator, you can often resolve the error. Remember to prioritize security and avoid actions that could compromise the system.
