May be the timeout is too short. Could you try to increase it and check
what happens?<br>

<br>
</font></div>
If the computer (on which this dead IOR has been generated) is switched
off then the<br>
only way to terminate a remote call is the timeout. TCP/IP (and
therefore CORBA) can't <br>
tell anything apart from there were no reply in certain amount of time.<br>
If you switch that machine on then most probably you will get another
minor code.<br>
<br>
Cheers,<br>
Sergei<br>
