title: Interesting variation of the TNSPING Message 3511 error
body: <p>I have the following problem with Oracle 11g TNSPING utility: fresh 11g client installation, ORACLE_HOME set up properly, TNS_ADMIN also set, msb files available in desired location, readable by the user that invokes TNSPING. Connection to the database works, sqlplus can be used to connect. TNSPING, however, fails badly. See attached log:</p>

  <p>Please note: I had to replace all the user credentials, database name, etc., due to security considerations.</p>
  
  <p>Can you help me, please, troubleshoot the issue? I have read all the other StackExchange topics related to TNSPING failure, but each of the solutions (set up ORACLE_HOME, reinstall, make sure registry points to proper home, check msb files) has failed me...</p>
  
  <p>Thanks in advance!</p>
