Failed login attempts are not shown in security event viewer

Hi,

 I have a domain which for some reason doesn't show failed login attempts, it only shows success for audit logon events. I've logged in via RDP to several Pc's on the domain with incorrect passwords to the point where the accounts are locked out, but still no logon failures show in the security log.

 I've configured the default domain policy to audit account logon events success + fail and audit logon events success, failure, but still no luck.

Pics attached - any ideas much appreciated.

Thx

you need to set this on the domian controller policy
all the dc are under the domian controller OU. so you need to look at the group policy applied here

If the user account has logged into the pc before then the logon failures should show up on the client security log.  Is that where you are looking?  The reason is that the credentails are cached on the client so it does not have to go to the DC to verify a correct username / password for this user.  The DC should however show the lockout for the account.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Dear friend , even though the above answer is correct , ever login failuer can be logged on the dc where the user authenticates . You need to enable audting on domain controler policy for this to work .

If would be tolally impractical to look at thousands of compter logs for invalid logon attempts .

Hope some one elase will be able to use this info
