If it held any FSMO roles you need to sieze them. Once all the roles are moved over do a DCPROMO / FORCEREMOVAL on the dead DC, do a metadata cleanup and reintroduce it as a DC if you want. When searching the internet you will probably find many possible causes and solutions. In my case, the following worked. Troubleshooting Kerberos Errors. Microsoft Corporation Published: March Abstract This white paper can help you troubleshoot Kerberos authentication problems that might occur in a Microsoft® Windows Server™ operating system environment. Hi All, We have an application server which sits on Vmware. I am receving multiple Kerberos erros on this server.

Through a network trace from the clients we saw that the Vista client was happily using NTLM authentication between the 2 clients, but the Windows 7 client was trying to acquire a “ User 2 User” Kerberos ticket from the KDC for the user object – the result was KDC_ ERR_ S_ PRINCIPAL_ UNKNOWN and we saw that an event 3 was being logged from. Kerberos related Result Code messages can appear on the authentication server KDC, the application server, at the user interface, or in network traces of Kerberos packets. Often a generic message will be presented at the user interface.

Active Directory Kerberos issue KDC_ ERR_ S_ PRINCIPAL_ UNKNOWN Hi, We are implementing a system where our clients are Windows XP and our server is Windows Server R2. Ive never had anything to do with Kerberos and know allmost nothing about it so really looking for some advice/ guidance, ive trawelled through various post and although they seem to know what there doing and talking about im not entirley sure it relates to my problem so thought i would post the errors and see if my fellow guru' s could lend a second head/ set of eyes : ). This conventional TGS exchange could be explained by the fact that the code that forces to transition to U2U is emulating the reception of the user- to- user required error, and thus after the point where we get the normal ticket. The document also shows you how to configure Kerberos authentication end- to- end within your environment, including scenarios which use various service applications in SharePoint Server. Additional tools and resources are described to help you test and validate Kerberos configuration.

    Table of Kerberos v5 Status Codes ( GSS- API Programming Guide) Docs. com Table of Kerberos v5 Status Codes.

The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc.

    , so I know a lot of things but not a lot about one thing. When user try to login on the workstation, he or she needs to provide correct username and password. Workstation will contact a domain controller ( DC) and try to obtain a Kerberos ticket for the user. Active Directory Documentation Team Active Directory Documentation Team Information for IT Professionals who work with Active Directory. All blog posts are provided " AS IS" with no warranties, and confer no rights. This group is exactly what enables the S4U2Self kerberos service generally for all user and computer accounts ( which were created after AD schema has been upgraded to its version). If you need to add the server' s account into the group, you then need to reboot the server. To troubleshoot Kerberos authentication, you need to understand how Kerberos authentication interacts with its supporting technologies ( such as Active Directory ® directory service and time servers) as well as how the Kerberos authentication process works. I wanted to create this blog to address one of the IIS Support teams top support issues. The issue is with allowing the identity of the user logged into a client machine, to pass through the IIS Server, and onto a back end server. Windows uses this event ID for both successful and failed service ticket requests. If it is a failure event see Failure Code: below. Whereas event ID 4768 lets you track initial logons through the granting of TGTs, this lets you monitor the granting of service tickets. Service tickets are obtained. If the username and password are correct and the user account passes status and restriction checks, the DC grants the TGT and logs event ID 4768 ( authentication ticket granted).

    If the ticket request fails Windows will either log this event, 4768 or 4771 with failure as the type. This event generates every time Key Distribution Center gets a Kerberos Ticket Granting Service ( TGS) ticket request. This event generates only on domain controllers. If TGS issue fails then you will see Failure event with Failure Code field not equal to “ 0x0”. You will typically see many. In this case Kerberos pre- authentication catches this at the domain controller and Windows logs event ID 675, " Pre- authentication failed", with Failure Code 24 in the event' s description ( see figure 2). Normally users should be edited in SU01 to enter the SNC data. This information is added to table USRACL. Do you have knowledge how we can automate this? This event generates every time Key Distribution Center issues a Kerberos Ticket Granting Ticket ( TGT). If TGT issue fails then you will see Failure event with Result Code field not equal to “ 0x0”. This event doesn' t generate for Result Codes. Stack Exchange network consists of 174 Q& A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. When we see this type of error, it is typically Kerberos related as the Service we are using ( ServerA) is unable to delegate the client’ s credentials to the backend server ( ServerB – Linked Server). A user account' s password or personal identification number ( PIN) can be stored on the local computer, which allows the user to log on to the computer without entering a password or PIN
