Users cannot authenticate to file server
I have a domain that I recently took from a 2003 SBS environment and upgraded the domain to a 2022 DC. I am randomly getting users trying to connect to our file server via servername (\\servername\share) either a shortcut or mapped drive and they will get a credential request with the error "The system cannot contact a domain controller to service the authentication request". They can immediately address the server via IP and all works fine. In the client event log i am finding Event 40960, LSA (LsaSrv) "The Security System detected an authentication error for the server cifs/servername. The failure code from authentication protocol Kerberos was "No authority could be contacted for authentication. (0x80090311)"." A client reboot will remedy the issue for a period of time.2.1KViews0likes7Comments
