[omniORB] looks like the ORB is not listening on a given port

Check the configuration of the Windows Firewall on the client computer.
It is configured to refuse most inbound connections by default.

Hi all,

First time posting to this group so bear with me:

We are using the OMNI ORB to work with a CORBA implementation at the
Chicago Board Options Exchange (CBOE). We have had our application
running successfully on a number of machines but have encountered a
problem with a recent install where messages sent from the CBOE in
response to our calls seem to be making it to our client but they are
not being read by our client ORB. 

The trace logs (attached) don't reveal anything unusual to my
(untrained) eye.

Ordinarily, when the ORB is up and running with our client application
one can telnet the client IP and port (in this case 8101) and establish
a session but when we try on this client we can't telnet the machine and
port so it seems to me that for some reason the ORB is not listening.

The system details are as follows:

*        Operating system is Windows 7 64 bit

*        omniORB version is 4.1.4-x86_win32-vs7

*        the client sends to the CBOE over port 8102 and receives via
port 8101

I have triple checked the settings (registry entry, ORB end point, host
file entry etc.). There is no firewall enabled. We've tested this
application on Windows 7 successfully before. 

If no-one has encountered this problem any suggestions on next steps for
troubleshooting would be much appreciated. 

Thanks,

Nicholas
