Further to this e-mail I was able to switch on tracing an extrapolate the
following information

Can anyone explain what we is going on here?

Subject: [omniORB] CORBA::COMM_FAILURE

We have been working on a project, to connect to a thirdparty system. We are
getting a COMM_FAILURE exception when trying to invoke a method on an object
reference. But we do have a valid object reference. Yet, when we use the
supplied, sample client, everything works fine. Does, anyone have any idea
why we would experience such an exception?

I have read the manual that comes with omni orb and it suggests to keep
retrying, but this does not explain what is happening, each and everytime.

Server on Solaris, client on NT, using omniorb 3.0.1
