Error meaning:

An "Error_Logon_Session_Collision" happens when someone tries to log in with the same account while already logged in.

This means they can't log in again until they end the first session, causing access problems.

Causes:

Potential reasons for an "Error_Logon_Session_Collision":

1. Shared accounts: Multiple users trying to log in to the same account at the same time.
2. Improper session termination: A previous session wasn't closed correctly, making the system think it's still active.
3. System misconfigurations: Incorrect permissions or settings that lead to conflicts with session IDs.
4. Network issues: Problems with the internet connection affecting the logon process.
5. Software bugs: Errors in the software that can cause problems during logging in.

4. Difficulty starting new instances of applications.
5. Interruptions in work and productivity.

Solutions:

Step 1: Make sure all users log out of their sessions properly. This helps prevent overlapping logon IDs.

Step 2: Regularly check for and update the system software. This keeps everything running smoothly and reduces conflicts.

Step 3: Set up session timeout settings. This will automatically log off users who are inactive for a certain period, making session IDs available for others.

Step 4: Use centralized user management tools to keep track of who is logged in. This helps manage active sessions better.

Step 5: Conduct regular audits of user access rights. This helps find and fix any unauthorized use of sessions.

Step 6: Provide training for users on how to log on and log off correctly. This can help prevent the "Error_Logon_Session_Collision" from happening.
