Event ID 532 – Logon Failure: The Specified User Account Has Expired

Event 532 is generated when the user's attempt to logon fails because the user's account has expired. This event is generated only for domain accounts, and not local accounts. This event is not to be confused with password expiration, which has the ID 535.

This log data provides the following information:

• User Name
• Domain

Additionally, in Windows Server 2003, the following information is also made available:

• Caller User Name
• Caller Domain
