Can not build TNS connection from remote station but local do

Question

invole local service name, however, once i do the same work to
build a new TNS service name by net assist at another (remote)
machine, it always prompt on: " target object is not availabe"
or something like this;
i wonder why the local TNS service connection can work(it seems

I entered the following message on Sep. 29th and have not yet received a reply so I'm repeating it here:
I could not get IIOP to work either remotely or locally on my server. My environment runs Oracle 8.1.6 under Windows 2000 Server.
Per Oracle documentation, I added:
DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = SERVERNAME)(PORT = 2481))
(PROTOCOL_STACK =
(PRESENTATION = GIOP)
(SESSION = RAW)
to my listener.ora file and:
mts_dispatchers="(protocol=tcp)(presentation=oracle.aurora.server.SGiopServer)"
to my init.ora file. When I used the sses_sh command I got the following first few lines:
"Exception in thread "main" org.omg.CORBA.COM_FAILURE[completed=MAYBE, reason = java.net.SocketException: Socket failed]..."
Looking at the log I got the following error:
"TNS-12516 TNS:listener could not find available handler with matching protocol stack".
I didn't see anything interesting in the trace file.
Is there something else I need to do to get the listener to find the proper protocol stack? Has anyone encountered and found the solution to this problem?
