Spotlight on Oracle
When connecting to the database, Spotlight displayed the following error:

The connection could not be established.
Details: Access Violation at address 77F64F03 in module 'ntdll.dll'. Write of address 000000 <OK>.

Clicking <OK> displays the Connection dialog window and then Spotight freezes and the user must End Task out of Spotlight.

NOTE: When connecting to the database, Spotlight looks at the SQLNet.ora file "Names.directory_path " parameter. This usually shows [Tnsnames, ONames, HOST, or LDAP, etc].

Example:
SQLNET.ORA file:
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES)

The SQLNet.ora file is located under the following path by default on the client machine.
C:\<Oracle_Home>\Network\Admin

To resolve this issue, please edit the SQLNet.ora file and move your primary SQL*Net method to the very front of the "Names.directory_path " parameter list . This will be "Tnsnames.ora" or "ONames" depending on which method used in your environment.
