Well,

I appreciated the few replies already received on my first call for
help in getting CU-SeeMe running on my system. The suggestion of timeouts
is a possible cause for the error message. However, in turning on the
tracing of DNS and UDP I found this during an attempt to connect to
"reflector.cit.cornell.edu":

Undelivered UDP <---- I suspect that this is where my trouble
starts. Am I going
UDP 520->520 64 through a firewall and being blocked
by it at this point??
UDP 7648->7648 56
UDP 7648->7648 56
UDP 7648->7648 56

So I do have a connection to the reflector. However, the CU-SeeMe windows
returns to the 'Waiting for a connection...' message and that's it! No
video, no sound ... no connection after that last UDP ... nada. Hope this
helps the ones in the know.
