Another ORA-28575 struggle

Question

I keep getting ORA-28757 errors when trying to make a call to an interMedia ORDSYS.ORDImage.process routine. Searched all of this forum and whatever I could find on Metalink. Followed all the directions, I believe. I also set my env param for TNS_ADMIN. My OS is NT4.0, DB is 8.1.6.
When I keyin
tnsping extproc_connection_data
at a command prompt, I get an OK. So I believe my listener.ora and tnsnames.ora and sqlnet.ora files are synchronized. I have checked my init.ora file and all mts entries are commented. Still get ORA-28575.
Can anyone help? I have included my tnsnames.ora and listner.ora entries below.
TIA

tnsnames entry is:
EXTPROC_CONNECTION_DATA.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
listener.ora entries are:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = jjc-nt)(PORT = 1521))
(DESCRIPTION =
(PROTOCOL_STACK =
(PRESENTATION = GIOP)
(SESSION = RAW)
(ADDRESS = (PROTOCOL = TCP)(HOST = jjc-nt)(PORT = 2481))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = F:\ora816)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = orcl2.jjcnt)
(ORACLE_HOME = F:\ora816)
(SID_NAME = orcl2)
(SID_DESC =
(GLOBAL_DBNAME = "d704.WORLD")
(ORACLE_HOME = F:\ora816)
(SID_NAME = D704)
(SID_DESC =
(GLOBAL_DBNAME = orcl8i.jjcnt.com)
(ORACLE_HOME = F:\ora816)
(SID_NAME = orcl8i)
Here's sqlnet.ora also:
NAME.DEFAULT_ZONE = world
NAMES.DEFAULT_DOMAIN = world
TRACE_LEVEL_CLIENT = OFF
NAMES.DIRECTORY_PATH= (TNSNAMES)
AUTOMATIC_IPC = OFF
null

Hi,
Looks like you've done just about everything. Here are a couple more suggestions to try to track this down.
First, double-check the init.ora file(s) to make sure that the LOCAL_LISTENER parameter associated with MTS isn't specified.
In the PL/SQL demo directory, there's an ExtProc debugging example. We can try that to see if its ExtProc calls in general that are failing, or just interMedia ExtProc calls.
First, cd to <oracle_home>\plsql\demo, run SQL*Plus, then:
SQL> connect system/<manager-password>
SQL> grant create any library to scott;
SQL> connect scott/tiger
SQL> @dbgextp
SQL> execute DEBUG_EXTPROC.STARTUP_EXTPROC_AGENT;
SQL> connect system/<manager-password>
SQL> revoke create any library from scott;If its a general ExtProc problem, then the execute should fail. As a matter of elimination, it might be worth trying this from each database, just to see if its limited to one instance. I've included some sample output below.
Let us know what you find.

Simon
