Hello, even if you have multiple event errors use only one posting for one machine as this belongs together: http://social.technet.microsoft.com/Forums/en/winservergen/thread/9f6bef17-d92e-46d9-89b8-42a431ba3a9eBest regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hi, This event error means that Kerberos cannot authenticate the Web program user because the server cannot verify the Kerberos authentication request sent by the client. This usually happens when there is an account in the target domain with the same name as the server in the client's domain. If so, the ticket is issued for the server in the client's domain and it cannot be decrypted by the recipient server in the target domain. To fix this issue, please search the client domain for accounts with the same name as the target server, and then either rename the duplicate account or remove it. For more information, please refer to the following TechNet article: Event ID 4 — Kerberos Client Configuration http://technet.microsoft.com/en-us/library/cc733987(WS.10).aspx For more troubleshooting information, please also refer to the following article: Event ID 4 Source Kerberos http://www.eventid.net/display.asp?eventid=4&eventno=1968&source=Kerberos&phase=1 Note: Since the web site is not hosted by Microsoft, the link may change without notice.
