data warehouse behavior. Basically, the issue I had was that my the kerberos client received a krb_ap_err_modified error from the server sql Data Warehouse jobs would fail to complete. At the same time, in the event viewer of my reset secure channel password domain controller systems I had the following error message : Log Name: System Source: Microsoft-Windows-Security-Kerberos Event ID: 4 Task Category: None Level: Error Keywords: Classic User: N/A Computer: SCSMDW.wsdemo.com Description: The https://support.microsoft.com/en-us/kb/558115 Kerberos client received a KRB_AP_ERR_MODIFIED error from the server smsvc. The target name used was MSOMSdkSvc/SCSMDW. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. Ensure that https://blogs.technet.microsoft.com/dcaro/2013/07/04/fixing-the-security-kerberos-4-error/ the target SPN is only registered on the account used by the server. This error can also happen if the target service account password is different than what is configured on the Kerberos Key Distribution Center for that target service. Ensure that the service on the server and the KDC are both configured to use the same password. If the server name is not fully qualified, and the target domain (WSDEMO.COM) is different from the client domain (WSDEMO.COM), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server. In my environment, smsvc is the service account that I’m using for Service Manager. However when I looked at my SPN settings, I had the following : C:\Users\Administrator.WSDEMO>setspn -Q MSOMSdkSvc/SCSMDW Checking domain DC=wsdemo,DC=com CN=SCSMDW,CN=Computers,DC=wsdemo,DC=com MSOMSdkSvc/SCSMDW MSOMSdkSvc/SCSMDW.wsdemo.com MSOMHSvc/SCSMDW MSOMHSvc/SCSMDW.wsdemo.com TERMSRV/SCSMDW TERMSRV/SCSMDW.wsdemo.com WSMAN/SCSMDW WSMAN/SCSMDW.wsdemo.com RestrictedKrbHost/SCSMDW HOST/SCSMDW RestrictedKrbHost/SCSMDW.wsdemo.com HOST/SCSMDW.wsdemo.com Existing SPN found!

The target name used was cifs/ceo-computer.domain.local. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name (SPN) is registered on kerberos client an account other than the account the target service is using. The message evaded me for quite a long time - it seemed to indicate a mismatch in computer names, but I knew quite well both were properly joined to the domain. I wondered what would happen if I tried a basic operation on the target machine? C:\System>dir the kerberos client \\ceo-computer\c$ Logon Failure: The target account name is incorrect. Interesting - something was going on with the account for ceo-computer$ I wonder if the machine is online and resolves to an IP address? C:\System>ping -n 1 ceo-computer Pinging ceo-computer.domain.local [10.0.0.36] with 32 bytes of data: Reply from 10.0.0.36: bytes=32 time<1ms TTL=128 Interesting - the machine is online. I wonder if they mean the computer account? A quick check would show me the NetBIOS machine name of that host: C:\System>nbtstat -A 10.0.0.36 Local Area Connection: Node IpAddress: [10.0.0.2] Scope Id: [] NetBIOS Remote Machine Name Table Name Type Status ------------------------------ RECEPTION-WIN7 <00> UNIQUE Registered DOMAIN      <00> GROUP Registered RECEPTION-WIN7 <20> UNIQUE Registered DOMAIN      <1E> GROUP Registered MAC Address = 00-0F-FB-F3-CF-73 And there we have it. When I issue the DIR command for the above UNC, it looks up the SPN for that machine and then looks the machine name up in DNS. The machine returned the IP address for a different computer, with the destination rejecting the connection because the l

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.
