　　This is a highly valuable event since it documents each and every successful attempt to logon to the local computer regardless of logon type, location of the user or type of account.
　　

Description Fields in 4624 Subject: 　　Identifies the account that requested the logon - NOT the user who just logged on.  Subject is usually Null or one of the Service principals and not usually useful information.  See New Logon for who just logged on to the sytem. Logon Type: 　　This is a valuable piece of information as it tells you HOW the user just logged on: Logon Type Description 2 Interactive (logon at keyboard and screen of system) 3 Network (i.e. connection to shared folder on this computer from elsewhere on network) 4 Batch (i.e. scheduled task) 5 Service (Service startup) 7 Unlock (i.e. unnattended workstation with password protected screen saver) 8 NetworkCleartext (Logon with credentials sent in the clear text. Most often indicates a logon to IIS with "basic authentication") See this article for more information. 9 NewCredentials such as with RunAs or mapping a network drive with alternate credentials.  This logon type does not seem to show up in any events.  If you want to track users attempting to logon with alternate credentials see 4648. 10 RemoteInteractive (Terminal Services, Remote Desktop or Remote Assistance) 11 CachedInteractive (logon with cached domain credentials such as when logging on to a laptop when away from the network) New Logon: 　　The user who just logged on is identified by the Account Name and Account Domain.  You can determine whether the account is local or domain by comparing the Account Domain to the computer name.  If they match, the account is a local account on that system, otherwise a domain account. Security ID: the SID of the accountAccount Name: Logon name of the accountAccoutn Domain: Domain name of the account (pre-Win2k domain name)Logon ID is a semi-unique (unique between reboots) number that identifies the logon session just initiated.  Any events logged subsequently during this logon session will report the same Logon ID through to the logoff event 4647 or 4634.Logon GUID: Supposedly you should be able to correlate logon events on this computer with corresonding authentication events on the domain controller using this GUID.  Such as linking 4624 on the member computer to 4769 on the DC.  But the GUIDs do not match between logon events on member computers and the authentication events on the domain controller. Process Information: 　　The Process Name identifies the program executable that processed the logon.  This is one of the trusted logon processes identified by 4611. Process ID is the process ID specified when the executable started as logged in 4688. Network Information: 　　This section identifies WHERE the user was when he logged on.  Of course if logon is initiated from the same computer this information will either be blank or reflect the same local computers. Workstation Name: is the computer name of the computer where the user is physically present in most cases unless this logon was intitiated by a server application acting on behalf of the user.  Workstation may also not be filled in for some Kerberos logons since the Kerberos protocol doesn't really care about the computer account in the case of user logons and therefore lacks any field for carrying workstation name in the ticket request message.Source Network Address is the IP address of the computer where the user is physically present in most cases unless this logon was intitiated by a server application acting on behalf of the user.  If this logon is initiated locally the IP address will sometimes be 127.0.0.1 instead of the local computer's actual IP address.  This field is also blank sometimes because Microsoft says "Not every code path in Windows Server 2003 is instrumented for IP address, so it's not always filled out."Source Port identifies the source TCP port of the logon request which seems useless since with most protocols source ports are random. Detailed Authentication Information: Logon Process (see 4611) CredPro indicates a logon initiated by User Account Control Authentication Package (see 4610 or 4622) Transited Services - This has to do with server applications that need to accept some other type of authentication from the client and then transition to Kerberos for accessing other resources on behalf of the client.  See http://msdn.microsoft.com/msdnmag/issues/03/04/SecurityBriefs/ Package name - If this logon was authenticated via the NTLM protocol (instead of Kerberos for instance) this field tells you which version of NTLM was used.  See security option "Network security: LAN Manager authentication level" Key Length - Length of key protecting the "secure channel".  See security option "Domain Member: Require strong (Windows 2000 or later) session key".  If value is 0 this would indicate security option "Domain Member: Digitally encrypt secure channel data (when possible)" failed. 　　Top 10 Events to Monitor Examples of 4624 　　An account was successfully logged on. 　　Subject:    Security ID:  SYSTEM    Account Name:  WIN-R9H529RIO4Y$    Account Domain:  WORKGROUP    Logon ID:  0x3e7 Logon Type:10 New Logon:       Security ID:  WIN-R9H529RIO4Y\Administrator    Account Name:  Administrator    Account Domain:  WIN-R9H529RIO4Y    Logon ID:  0x19f4c    Logon GUID:  {00000000-0000-0000-0000-000000000000} Process Information:    Process ID:  0x4c0    Process Name:  C:\Windows\System32\winlogon.exe Network Information:      Workstation Name: WIN-R9H529RIO4Y    Source Network Address: 10.42.42.211    Source Port:  1181 Detailed Authentication Information:      Logon Process:  User32    Authentication Package: Negotiate    Transited Services: -    Package Name (NTLM only): -    Key Length:  0 This event is generated when a logon session is created. It is generated on the computer that was accessed. 　　The subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe. 　　The logon type field indicates the kind of logon that occurred. The most common types are 2 (interactive) and 3 (network). 　　The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on. 　　The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases. 　　The authentication information fields provide detailed information about this specific logon request. 　　The authentication information fields provide detailed information about this specific logon request. Logon GUID is a unique identifier that can be used to correlate this event with a KDC event. Transited services indicate which intermediate services have participated in this logon request. Package name indicates which sub-protocol was used among the NTLM protocols. Key length indicates the length of the generated session key. This will be 0 if no session key was requested.
