What do you mean by "client level", "violating something" or "probably not compatible with a specific setting" What settings are you referring to?
Group policies were examined to ensure there were not any password policy violations. Anyway these would have resulted in a different Kerberos error code.
Office Office Exchange Server. Not an IT pro? Resources for IT Professionals. When a client requests a service ticket that it can pass along the DC issues it. The client then sends it to the remote host it's trying to authenticate to. In this scenario, the remote server can't decrypt the ticket the client sent to it since the password used to encrypt it isn't the right one. That, in turn, is the result of the SPN for that service and ticket being on the incorrect object in AD. It is that other objects password that is used instead.
In this scenario, the server who can't decrypt the ticket responds to the client. The client then puts Kerberos event 4 example below in its System event log. Less commonly this is caused by network problems between client and server where the ticket is truncated. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named machine accounts in the target realm childdomain. Indicates that a ticket was issued using the authentication service AS exchange and not issued based on a TGT.
Indicates that the client was authenticated by the KDC before a ticket was issued. This flag usually indicates the presence of an authenticator in the ticket. It can also flag the presence of credentials taken from a smart card logon.
This flag was originally intended to indicate that hardware-supported authentication was used during pre-authentication. This flag is no longer recommended in the Kerberos V5 protocol.
If this flag is set in the request, checking of the transited field is disabled. The RENEWABLE-OK option indicates that a renewable ticket will be acceptable if a ticket with the requested life cannot otherwise be provided, in which case a renewable ticket may be issued with a renew-till equal to the requested end time.
The value of the renew-till field may still be limited by local limits, or limits selected by the individual principal or server. The ticket provided is encrypted in the secret key for the server on which it is valid. The ticket to be renewed is passed in the padata field as part of the authentication header. This option is used only by the ticket-granting service.
Should not be in use, because postdated tickets are not supported by KILE. Smart card logon is being attempted and the proper certificate cannot be located. This problem can happen because the wrong certification authority CA is being queried or the proper CA cannot be contacted in order to get Domain Controller or Domain Controller Authentication certificates for the domain controller. This type should also be used for Smart Card authentication, but in certain Active Directory environments, it is never seen.
Supported starting from Windows Server domain controllers and Windows 8 clients. High-value accounts : You might have high-value domain or local accounts for which you need to monitor each action. Examples of high-value accounts are database administrators, built-in local administrator account, domain administrators, service accounts, domain controller accounts and so on. Anomalies or malicious actions : You might have specific requirements for detecting anomalies or monitoring potential malicious actions.
For example, you might need to monitor for use of an account outside of working hours. Non-active accounts : You might have non-active, disabled, or guest accounts, or other accounts that should never be used. Account allow list : You might have a specific allow list of accounts that are the only ones allowed to perform actions corresponding to particular events.
