I have fully patched all DC's and still receiving Event 37, Kerberos-Key-Distribution-Center repeatedly on accounts. I read that you should get one per user, I am getting multiple per user, per day.

I am not sure what else to do at this point. I am having issues with RDP, and other kerberos related authentication. The only way around the RDP auth issue is to use the IP address, or sometimes to reboot DC's.

App servers will fail SSO using Kerberos, which requires a reboot of the DC that the user is authenticating from.
