The Security System Detected An Authentication Error For The Server Ldap


My solution is probably only applicable to domain controllers running the DNS server service. What is Kerberos? These errors seem to be generated by programs trying to resolve domain names to connect back to the server to authenticate, but can't find it if the DNS server service hasn't http://theether.net/kb/100040
