[tao-users] Initialization Problem

Hi all,

I'm trying to diagnose a problem that is only happening very rarely (on
Windows). I have two local processes communicating via ACE/TAO. The server
is successfully initializing but the client is failing on certain machines
(it happens on very, very few machines but is 100% reproducible on the
machines that fail). I increased the debug levels to see if I couldn't get
a hint of what is happening.  Typically when we see similar problems, they
are related to port conflicts but in this case, the server is able to bind
the port successfully and the client simply cannot connect to it.

I'm fairly convinced that the problem is related to the OS configuration,
or perhaps some restrictive software (e.g. firewall).  However, I've
exhausted all known options. Maybe someone who is more experienced with
ACE/TAO could lend some advice about things to try.

Here is the debug output:
