Re: Event ID 40960 & 40960 - Kerberos Authentication Error

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Does it show any problems communicating with other domain members? Does the
SQL server machine permit tcp and udp traffic over port 88 (Kerberos)?

Hi There,
I have the following problem and would greatly appreciate any assistance to
help me resolve it (after trying lots of avenues without success)?

The System Event log on my Winodwss 2003 domain controller shows the

(OS also Winodws 2003 server). This warning repeatedly appears in the
system log.
