C0s>реально я бы посоветовал:
C0s>1) убедиться, что серверный объект живёт и дышит
C0s>2) убедиться, что IOR, полученный из ns, соответствует этому объекту
C0s>3) взять в руки сниффер, чтобы потрейсить сетевую активность клиента

Серверный объект живёт, тестил другой софтиной(тоже коннектится к этой корбе и выполняет те же функции)
Сниффер говорит следующее

убедиться, что IOR, полученный из ns, соответствует этому объекту
Я честно говоря не знаю как это сделать
