The error code 0x00000046 translates to “DEREF_UNKNOWN_LOGON_SESSION” on Windows systems. This error code is very uncommon and primarily relevant for programmers debugging Windows drivers. Here’s what you need to know:

Cause:

  • Buggy or Incompatible Driver: The most likely culprit is a faulty or incompatible device driver that attempts to dereference (access) a memory location associated with an unknown or invalid logon session. Logon sessions manage user access to the system. An unknown session pointer can indicate a bug within the driver.

Troubleshooting (for programmers):

Since this error is specific to driver development and debugging, these steps are meant for programmers analyzing the problematic driver code. If you’re not a programmer, consider seeking help from a qualified technician to diagnose the issue.

  • Driver Code Analysis: Analyze the driver code to identify where it attempts to dereference a logon session pointer. Look for situations where the driver might be using outdated or incorrect methods for accessing session information.
  • Driver Updates: If the driver is from a third-party vendor, check for updates or bug fixes that might address the issue.
  • Debugging Tools: Use kernel debugging tools to pinpoint the exact location within the driver code where the dereference error occurs.

Additional Considerations:

  • Limited Use Case: This error is primarily encountered by programmers working on device drivers. For regular users, it’s less common.

Resources:

While there aren’t many publicly available resources specifically for this error code due to its rarity, here are some that might be helpful for programmers:

If you’re not a programmer:

  • Consider seeking help from a qualified technician who can diagnose the issue and identify the problematic driver.
  • If the error is happening on your personal computer and you’re not comfortable troubleshooting drivers, you can try:
    • Updating your Windows system and all device drivers to the latest versions.
    • Booting your computer into Safe Mode to see if the error occurs there (Safe Mode loads only essential drivers). If the error doesn’t happen in Safe Mode, it suggests a problem with a non-essential driver.

Remember: Modifying or replacing system drivers can be risky if done incorrectly. It’s recommended to seek professional help if you’re not comfortable with driver troubleshooting.
