DC Kerberos Security Traffic

Our network has a Cisco WLC and 3 DC's. We use a Windows 2016 NPS server for client authentication to the network. The issue I face is that even though the user (using domain and non domain devices) authenticates correctly with the NPS server, not all the Kerberos details are showing on the DC's. Has anyone had an issue when the not all Kerberos traffic is not being forwarded to a DC ?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

you would need to check all 3 DC's in order to see which one is running the authentication.

What are your symptoms?

Have you used eventcombMT to pull the logs from all DC's and then gone through those?

Thanks

Hi Alex

Yes I did check all the DC's event logs. The thing is it is really intermittent. I enabled the auditing via a GPO as you can't add a local policy on DC's. I believe that all DC's should be running authentication for clients.

All DC's will be running authentication, it just depends where the client goes to, to run that authentication :-)

 have you run a DCDIAG to see if there is an issue there?

Thanks
