Krb_ap_err_modified Domain Controller
vote Hi, since one night i receive the following error message on all member Server in resetting the secure channel pw of a broken domain controller a branch office for a special subent.

This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. Please ensure that the target SPN is registered on, and only registered on, the account used by the server. This error can also happen when the target ervice is using a different password for the target service account than what the Kerberos Key Distribution Center (KDC) has for the target service account. Please ensure that the service on the server and the KDC are both updated to use the current password. If the server name is not fully qualified, and the target domain (domain.local) is different from the client domain (domain.local), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server. These servers have no routing to the local Domain Controllers, instead they contact the DCs at the main office. So the KRB_AP_ERR_MODIFIED err

Event Type:ErrorEvent Source:KerberosEvent Category:NoneEvent ID:4Computer:SE-SMURF01Description:The kerberos client received a KRB_AP_ERR_MODIFIED error from the server PC-BLA09$. The target name used was RPCSS/PC-BLA10. 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 (FOO.BAR.STRIPE.LOCAL), and the client realm. Please contact your system administrator. I had replaced those machines a week ago, and everything seemed to work fine. So I didn't understand why these errors were suddenly popping up. The applications running on those computers where throwing a wobbler as well. Some googling later I found 2 remarks that were useful. The first one was that someone fixed it by taking the computer out of the domain, renaming it, changing the SID, and changing the IP address. While this is overkill on the scale of killing a mouse with a thermonuclear weapon, it pointed in the direction of a network level problem. The second remark was by a Microsoft employee who explained that DNS misconfiguration can be the source of problems like this. If kerberos thinks it is communicating with pcA it encrypts the kerb ticket with the password of pcA. but if the ticket then ends up on pcB because of the DNS mismatch, the above events will be logged. At that moment I realized that I had changed the IP address of an adapter on PC-BLA10 because it conflicted with PC-BLA09. The reason everything worked fine initially was because that port had been left disconnected until 2 days ago when I configured the correct IP address. The conflict was resolved and the DNS information was updated, but that didn't mean that the DNS caches were up to date. So I cleared the DNS cache of the DNS server, and used ipconfig /flushdns to clear the resolver cache on the domain controller and PC-BLA10, and the problem disappeared.
