Q10090 - HOWTO: Decoding the Windows Account Logon Error Code

The information in this article applies to:

  • Windows security event log entries

SUMMARY

Windows security log entries for failures of an account logon include an Error Code. This article describes how to interpret those entries.

MORE INFORMATION

A Windows logon failure will typically indicate to the user only that the user name is unknown or that the password is bad. Sometimes it would be useful to know which of these is the case. Of course, disclosing this information to an unknown network user could lessen security, but the information may still be obtained from the event log.

The Error Code field will provide some detail as to why the logon attempt failed. These values may appear there:
