Error -2146893052 (0x80090304): The Local Security Authority cannot be contacted.
This error is seen in the SQL Server ERRORLOG file. This is an Active Directory error; Windows could not connect to the local security subsystem (LSASS). The System Event Log may also log SCHANNEL, KERBEROS, or NETLOGON events related to this error message. This should be troubleshot as an Active Directory issue and not a SQL Connectivity issue.
All it does is empower misroutes to DS to reverse engineer a SQL application.
