I tried to configure Windows 7 machine with our web-server running on it to log Kerberos-related events (meaning Windows system Log). I followed these instructions: How to enable Kerberos event logging. In order to test this setting, I changed time on a demo client machine so that 'Clock skew too great' error would be raised. The exception itself was raised on a server, however, no logs were found in System Log. Even though I expect them to be logged only on a server machine, I also checked logs the same way on client machine, and even on a domain machine (which was rather a wild guess). As expected, no error events were found in system log.
I was trying this too, but it didn't work for me either, probably because Windows 7 is not listed in the "Applies to" section the link.
