Multiple events received for a single logon

Overview

Multiple events are being received for a single logon from the Domain Controller.

Environment

  • All LEM versions
  • Windows Environment

Cause 

This can occur when you are searching for User.Logon type events in LEM.

For example, the following shows two events received by LEM for the same action:

event comparison

4624  An account was successfully logged on

4776  The domain controller attempted to validate the credentials for an account

Resolution

Instead of using UserLogon as your filter or trigger, determine and use the relevant Windows EventID.

In LEM, this can be done by using ProviderSID to provide a more concise scope for the search.

example filter

Note: Where an agent is installed on a workstation and there are two Domain Controllers, it is possible that a Logon event may be sent to LEM from three different sources. For a list of Windows EventIDs, see Here.
