How to fix Win32 0x00000556 Error? ERROR_LOGON_SESSION_COLLISION
The error code Win32 0x00000556 translates to ERROR_LOGON_SESSION_COLLISION, indicating a conflict between two login attempts. This typically occurs when you try to establish a new login session while a previous session with the same username or ID already exists.
Here’s a breakdown of the error and potential troubleshooting steps:
Understanding the Error:
- Login sessions are unique identifiers assigned to user login activities. Ideally, only one session with a specific username or ID can exist at a time.
- This error arises when you attempt to log in, but the system detects an existing session using the same credentials or session ID. This can happen due to various reasons.
Common Causes:
- Multiple Login Attempts: You might have accidentally initiated multiple login attempts, and one of them hasn’t completed or timed out yet, causing the session ID conflict.
- Previous Login Not Terminated Properly: An abnormal system shutdown or unexpected termination of a previous login session could leave a lingering session, preventing a new login attempt with the same credentials.
- Remote Desktop Session (Less Likely): In rare scenarios, if you’re using Remote Desktop and haven’t properly disconnected from a previous session, it might lead to a conflicting session ID.
Troubleshooting Steps:
Here’s how you can address the ERROR_LOGON_SESSION_COLLISION error:
-
Wait and Retry:
- Sometimes, a simple wait of a few minutes allows enough time for the conflicting session ID to expire or resolve itself. Try logging in again after a short wait.
-
Restart the Computer:
- Rebooting the computer clears out temporary system states and lingering session information. A restart can often resolve the issue by clearing the conflicting session.
-
End Remote Desktop Sessions (if applicable):
- If you’re using Remote Desktop, ensure you’ve properly disconnected from any previous sessions. Check for lingering remote desktop connections and terminate them if necessary.
-
Check for Frozen Sessions (For Administrators):
- If you’re a system administrator, you might have tools to check for active sessions and potentially terminate orphaned or frozen sessions that could be causing conflicts. However, proceed with caution to avoid disrupting other users’ sessions accidentally.
-
Consider Changing Password (if applicable):
- In extreme cases, if you suspect unauthorized access attempts or compromised credentials, consider changing your password to prevent further login attempts using your credentials.
-
System Administrator Involvement (For Complexities):
- If the error persists or you suspect a more complex issue, involving your system administrator is recommended. They can utilize advanced tools and techniques to diagnose the root cause and potentially reset session IDs if necessary.
In Summary:
The Win32 0x00000556 error (ERROR_LOGON_SESSION_COLLISION) indicates a conflict between login attempts. By waiting a short while, restarting the computer, or properly ending remote desktop sessions (if applicable), you can often resolve the issue. If the error persists, consider consulting your system administrator, especially if you suspect unauthorized access attempts.
