Filter get-eventlog by the subjects account name-CodePudding

I've created a little script that runs on our districts domain controllers that sends out an email any time a user is created in AD to our networking team. The script works great, but we want to filter out our MIM system that creates new users every morning based on new student intake and newly hired employees. Here is an example of the event that triggers when our MIM system creates a user.

A user account was created.

Subject:

Security ID:        NSD\srvMIMADMA

Account Name:       srvMIMADMA

Account Domain:     NSD

Logon ID:       0x564EF2A6

Here is the script I am using.

#---Generate email on new ADS account creation---#

$event = get-eventlog -LogName Security -InstanceId "4720" -Newest 1
$EmailBody = $event.Message

if ($event.EntryType -eq "Success" -and $event.UserName -ne "NSD\srvMIMADMA" -and $event.EventID -eq "4720")
{
    $mail = @{
            from        = "[email protected]"
            to          = "[email protected]"
            cc          = @("[email protected]", "[email protected]")
            subject     = "New AD user was created"
            smtpserver  = "10.10.10.10"
            port        = "PORT"
            body        = $EmailBody
            }
    
    Write-host "Sending Email"
    
    Send-MailMessage @mail
}
else
{
    write-host "No error found"
    write-host "Here is the log entry that was inspected:"
    $event
}

I was attempting to use event.UserName to filter out our MIM system, but that looks like its not working because our team got an email for it this morning. Is there a way to filter out events generated by a specific user?

CodePudding user response：

Try this

$event.Message -like "*NSD\srvMIMADMA*"

$event.Message -notlike "*NSD\srvMIMADMA*"

instead of

$event.UserName -ne "NSD\srvMIMADMA"
