listener hangs

I installed oracle 8.1.7 on windows 2000 m/c. The installed completed succesfully. I see the tnslistener serveice is started throught the windows services. When I run lstnrctl stop it stops the listener but when I run the lstnrctl start it just hangs.

When I am trying to create a database using the db configuration assitant it fails complaining 12560: TNS protocol adapter error. I have re-installed couple of times but same problem.

I got the following error the first time
=========================================

Failed to open service , error 1060.


listener.ora looks like the following.
======================================
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.250.150.121)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oracle\ora81)
(PROGRAM = extproc)
)
)

In my listener on my local box I have this listed

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\ora92)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = Smokey)
(ORACLE_HOME = D:\oracle\ora92)
(SID_NAME = Smokey)
)

I named the database instance Smokey, is there anything more in your listener file?
