Account Lockout

Updated: November 25, 2009

Applies To: Windows Server 2008 R2

The Security Accounts Manager (SAM) is a service that is used during the logon process. The SAM maintains user account information, including groups to which a user belongs. The SAM is attempting to lock out the account that exceeded the threshold for the number of incorrect passwords entered.


Event ID Source Message



The SAM database was unable to lockout the account of %1 due to a resource error, such as a hard disk write failure (the specific error code is in the error data) . Accounts are locked after a certain number of bad passwords are provided so please consider resetting the password of the account mentioned above.
