David,

Thanks you for your reply. Just wanted to let you know that I already
resolved this issue a couple of days ago by opening a case with the support
team.  As it turned out I think it would have taken several weeks to get to
the resolution of the issue using this online support venue. The support
engineers used Live Meeting to access my machine.  Even with direct access to
my machine it took well over an hour to diagnose the problem, which turned
out to be that somehow my DCOM service was configured for the local machine
and not network enabled.  After making this adjustment I have not had the
problem described.

Regards,
--Richard
