Can't start listener from OEM. It appears as Stopped although it is not.

Question

Hi,
I can't make the EM show the listener as running, it always shows it as stopped. I checked it with lsnrctl and it is running, but in EM appears as stopped. I refreshed the screen and nothing; I tried to start it from the EM, and it displays a message like "The listener has been correctly started", but when I check the status in EM it is still stopped. And when I check the details, it shows an error "Access denied", NET_ADMIN_ERROR,REMOTE_OP_ERROR,No such file or directory. I think I have the right credentials (I'm in the administrators group, and I have log on as batch job)
I would appreciate any help on this.
Thanks a lot
Ricardo

Hi Nicolas- here's the SQLNet and listener file:
-----------------LISTENER
# listener.ora Network Configuration File: C:\oracle\product\10.1.0\Db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
LISTENER2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
jon =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-----------------SQLNET
# sqlnet.ora Network Configuration File: C:\oracle\product\10.1.0\Db_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
#SQLNET.AUTHENTICATION_SERVICES= (NTS)
#NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
I can't see any excess protocols in the listener. As per some metalink entries - I've commented out the "SQLNET.AUTHENTICATION_SERVICES= (NTS)" line from the SQLNet file.
Still the same problem.
To be honest - all replies to postings for this error have not worked. I've contacted some guys with the same problem - and their resolution was to completely reinstall XP and then Oracle again. Just removing and reinstall Oracle was insufficient. So - i guess i'm going to have to follow suit.
Any last minute suggestions before this bit of drastic action?!
