EventID 540 - Successful Network Logon [Win 2003]
Indicates that a logon session was successfully created for the user logging in remotely to access a network resource (e.g. a file share).

The message contains the Logon ID, a number that is generated when a user logs on to a computer. The Logon ID is unique to that logon session until the computer is restarted, at which point the Logon ID may be reused. The Logon ID can be used to correlate a logon message with other messages, such as object access messages.
For logons that use Kerberos, the logon GUID can be used to associate a logon event on this computer with an account logon event on an authenticating computer, such as a domain controller.
This event is logged whenever a user logs on either with its local SAM account or a domain account.
This message also includes a logon type code. The logon type code indicates the manner in which the user logged on.
