Sql error 18456 state 10
To create an SPN for the FQDN of the SQL Server we use the following command: setspn -A MSSQLSvc/:1433 To create an SPN for the NetBIOS name of the SQL Server we use the following command: setspn –A MSSQLSvc/:1433 We can manually register SPN as a Domain Administrator. Reboot the misbehaving Domain Controller.Usually, this will affect registry change. Then add DWORD value “ DisableLoopbackCheck”.Go to: HKLM\System\CurrentControlSet\Control\LSA.Let us now focus on some methods our Support Engineers suggest in order to fix this error. SSPI handshake errors can be Time/Clock difference between the client clock differs server clock.If we don’t see anything starting with MSSQLSvc\ then the account is not set up with SPN.
We can check if the service account already has SPN, by running: setspn -l To use Kerberos, the client and SQL Server must be in the same domain and a Service Principal Name (SPN) must be registered with Active Directory for the SQL Server service account. If we only see NTLM and SQL then, there is no Kerberos connection. SELECT distinct auth_scheme FROM sys.dm_exec_connections To confirm if we have any database connection using Kerberos authentication, run: Failed Kerberos Authentication to connect to SQL Server.The connection would work, but it would kick down to NTLM. SQL Server engine account running with a Domain service account, and that account locked at the time a Kerberos connection attempt.This may register on the SQL Server error log due to Kerberos failure. However, if it fails, we can establish a connection using NTLM. In Windows 2003 and above, the default method of establishing a connection is Kerberos. This error can happen due to the Active Directory configuration issue or Network related issues.
