See security option "Network security: LAN Manager authentication level"
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. 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. 
Authentication Package: (see 4610 or 4622). Source Port: Identifies the source TCP port of the logon request which seems useless since with most protocols' source ports are random. #Dabble login code
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." 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.
Source Network Address: The IP address of the computer where the user is physically present in most cases unless this logon was initiated 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. Workstation Name: The computer name of the computer where the user is physically present in most cases unless this logon was initiated by a server application acting on behalf of the user. Of course if logon is initiated from the same computer this information will either be blank or reflect the same local computers. This section identifies where the user was when he logged on. This is one of the trusted logon processes identified by 4611. Caller Process Name: Identifies the program executable that processed the logon. Caller Process ID: The process ID specified when the executable started as logged in 4688. The user has not been granted the requested logon type (aka logon right) at this machine #Dabble login password

Status and Sub Status: Hexadecimal codes explaining the logon failure reason. Failure Reason: textual explanation of logon failure. The section explains why the logon failed. Account Domain: The domain or - in the case of local accounts - computer name. Account Name: The account logon name specified in the logon attempt. This blank or NULL SID if a valid account was not identified - such as where the username specified does not correspond to a valid account logon name. Security ID: The SID of the account that attempted to logon. This identifies the user that attempted to logon and failed. This is a valuable piece of information as it tells you HOW the user just logged on: See 4624 for a table of logon type codes. 
See New Logon for who just logged on to the system. Subject is usually Null or one of the Service principals and not usually useful information. Identifies the account that requested the logon - NOT the user who just attempted logged on.

This is a useful event because it documents each and every failed attempt to logon to the local computer regardless of logon type, location of the user or type of account.
