I suspect that the problem is that you're misinterpreting both error messages,
and therefore not taking appropriate action in response.  First, be aware
that VMS doesn't believe in lowercase filenames;  That means, for a VMS
machine, that by the time the remote task is set up, the name of the task
has been converted to uppercase, and I suspect that this happens on the
local, not the remote, node.  If this is the case, and if the name of the
task on the ULTRIX node contains lowercase characters, then when the message
says "network object is unknown at remote node", the task it is referring
to is "remfil", not TASK".  The solution in this case would be to rename
"remfil" to "REMFIL" on the ULTRIX node.  Similarly, for the second error
message, I suspect that the reason RMS is complaining is that "remfil" has
the executable bit set on the ULTRIX node.  Note that you were not talking
to "the Ultrix default", whatever the hell you meant by that;  you were
talking to FAL, the File Access Listener, on the Ultrix node, and the complaint
is that there's something in the way the file on the Ultrix node is set
up that makes it impossible to make a "reasonable" copy of it on a VMS system.
At any rate, the fact that you can't copy whatever file "remfil" might be
to the VMS system is probably unrelated to your inability to execute the
task.  Oh, by the way, another solution to the first problem MIGHT be
to use the task specification "TASK=""remfil""".  This should force it to
preserve lowercase;  VMS doesn't like it, but it's the remote node that
objects, so presumably the extra quotes are working.
