For information about the type of logon, see the Logon Types table below. #529 Logon failure. A logon attempt was made with an unknown user name or a known user name with a bad password. #530 Logon failure. A logon attempt was made user account tried to log on outside of the allowed time. #531 Logon failure. A logon attempt was made using a disabled account. #532 Logon failure. A logon attempt was made using an expired account. #533 Logon failure. A logon attempt was made by a user who is not allowed to log on at this computer. #534 Logon failure. The user attempted to log on with a type that is not allowed. #535 Logon failure. The password for the specified account has expired. #536 Logon failure. The Net Logon service is not active. #537 Logon failure. The logon attempt failed for other reasons. # Note # In some cases, the reason for the logon failure may not be known. #538 The logoff process was completed for a user. #539 Logon failure. The account was locked out at the time the logon attempt was made. #540 A user successfully logged on to a network. #541 Main mode Internet Key Exchange (IKE) authentication was completed between the local computer and the listed peer identity (establishing a security association), or quick mode has established a data channel. #542 A data channel was terminated. #543 Main mode was terminated. # Note # This might occur as a result of the time limit on the security association expiring (the default is eight hours), policy changes, or peer termination. #544 Main mode authentication failed because the peer did not provide a valid certificate or the signature was not validated. #545 Main mode authentication failed because of a Kerberos failure or a password that is not valid. #546 IKE security association establishment failed because the peer sent a proposal that is not valid. A packet was received that contained data that is not valid. #547 A failure occurred during an IKE handshake. #548 Logon failure. The security ID (SID) from a trusted domain does not match the account domain SID of the client. #549 Logon failure. All SIDs corresponding to untrusted namespaces were filtered out during an authentication across forests. #550 Notification message that could indicate a possible denial-of-service attack. #551 A user initiated the logoff process. #552 A user successfully logged on to a computer using explicit credentials while already logged on as a different user. #682 A user has reconnected to a disconnected terminal server session. #683 A user disconnected a terminal server session without logging off. # Note # This event is generated when a user is connected to a terminal server session over the network. It appears on the terminal server. #Logon type Logon title Description #2 Interactive A user logged on to this computer. #3 Network A user or computer logged on to this computer from the network. #4 Batch Batch logon type is used by batch servers, where processes may be executing on behalf of a user without their direct intervention. #5 Service A service was started by the Service Control Manager. #7 Unlock This workstation was unlocked. #8 NetworkCleartext A user logged on to this computer from the network. The user's password was passed to the authentication package in its unhashed form. The built-in authentication packages all hash credentials before sending them across the network. The credentials do not traverse the network in plaintext (also called cleartext). #9 NewCredentials A caller cloned its current token and specified new credentials for outbound connections. The new logon session has the same local identity, but uses different credentials for other network connections. #10 RemoteInteractive A user logged on to this computer remotely using Terminal Services or Remote Desktop. #11 CachedInteractive A user logged on to this computer with network credentials that were stored locally on the computer. The domain controller was not contacted to verify the credentials. |
