From a newsgroup post: "I understand that in your SBS 2003 server, you get event ID 5 with a KRB_AP_ERR_TKT_NYV error. I would like to provide the following action plan:
1. Open the service console; check if the W32Time service is running.
2. On client computers, check the TIME Zone settings to make sure that all the client workstations and SBS server 2003 have the same time zone configuration.
3. Go to command prompt, type net time /setsntp: <SBS server name>. For detailed steps, please refer to ME258059
. The article applies to Windows Server 2003 also.
Note: If there are any third party time sync programs running on the server, please go to Add/Remove programs and uninstall them.
4. Restart the computer and check if the problem is resolved. If the issue still exists, refer to ME325850
to reset the computer account password. Then restart computer and check again.
If the issue still occurs, please manually synchronize the time from the client PCs. To do so, please refer to ME314090
See "Troubleshooting Kerberos Errors" for a white paper that can help you troubleshoot Kerberos authentication problems that might occur in a Microsoft Windows Server 2003 operating system environment.
