Hello, 

Iam getting every few minutes a message that tells me that the account GUESTS is getting locked.

The domain guest account is disabled in our domain(i didn't know that a disabled account can be locked)

also the real username of guest account is changed to something else.0

i am getting thos messages fron my dc's.

what can it be? any idea ?

    Hi Benybb, sorry for delay. If we're talking about eliminating the root cause, then I think this article has some info about workarounds: https://social.technet.microsoft.com/Forums/windowsserver/en-US/df9255bf-f28d-4acf-b6c1-25ce041cc416/domainguest-account-being-locked-out-via-nondomain-joined-workstations?forum=winserverDS .

    If you are trying to understand why InTrust is sending you these messages, we can continue. InTrust predefined set includes 2 rules around lockout: "User Account Locked Out" based on Windows security event 4740 and "Failed Logon Due to User Account Lockout" based on Windows security event 4625 having "Failure Information: Status: 0xc0000234". Which of these two do you receive? In both cases you can trace back to the original Windows event using event ID and time, and the picture should get more clear. If not, please publish the original Windows event here. Thank you.

        Thank you for Response 

        Since i've found that its our Anti Virus Server (which is in the domain) that is causing that .. We are still investigating why..
        Anyway' my problem was that in the "ACCOUNT LOCKED OUT" rule didn't mention who or what  is causing this - only mentioned the "dc" as origin  ...

        It took me a while to discover that it is coming from the antivirus server - how can you help me with that for the next time please ?

        Thanks in advance

          Agree, good point, the notification doesn't contain this "Caller Computer Name" field. To add it, edit the rule and on the Alert tab of the "User Account Locked Out" rule change the Description from "User account %Target Account Name% locked out." to "User account %Target Account Name% locked out. Caller Computer Name: %String2%."

            Thanks for that - i appreciate - i discovered the problem ..

            My antivirus server is member of another domain , so i think that is why he tried first with guest and then with the right dredentials...

            Can you please help me to filter out a copmputer name in thie rule :

            User Account LOcked out

            Thanks in advance

                I am sorry ,I've probably din't explain myself good enough..

                I wish to have the possibility to exclude workstations from the rule itself .

                I am talking about the "matching" tab .

                Can you help me with that please ?

                  What do you think about excluding this computer from the site? I mean do not send this rule to this computer at all. This is the proper way instead of sending the rule and modifying it so that it will not work here. What do you think?

                  • 0 over 4 years ago in reply to Igor.Ilyin

                    i just wantedfor the rule to ignore this server and to not send me alerts about it 

                    because this server is in another domain...

                    i hope you understand what i am telling..

                      Oh, sorry, this alert comes from DC. OK.
