Listener problems: TNS-12500, TNS-12560, TNS-00530

Question

Dear All,
On a laptop (name: aspire3000, 1G RAM, 2GHz, Windows XP) I have installed Oracle 9i release 2 database (name=HOMEDB, sid=SIDHOMEDB). I "played" for a while trying to configure Oracle Shared Server but I think I've ruined the listener.
I execute the following steps:
1. start the PC
2. start the listener and database services in Control Panel (because they are set on manual)
3. in order to test the listener is functioning properly I execute:
lsnrctl> stop
lsnrctl> start
the listener starts, everything is ok
4. using sqlplus connected as sysadmin
4.1. sql> shutdown
it shuts down the database
4.2. sql> startup
Now, I receive:
ORA-12500: TNS: listener failed to start a dedicated server process
I check the sqlnet.log file:
Fatal NI connect error 12638, connecting to:
(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
VERSION INFORMATION:
     TNS for 32-bit Windows: Version 9.2.0.1.0 - Production
     Oracle Bequeath NT Protocol Adapter for 32-bit Windows: Version 9.2.0.1.0 - Production
Time: 21-FEB-2006 16:24:07
Tracing not turned on.
Tns error struct:
nr err code: 0
ns main err code: 12638
TNS-12638: Credential retrieval failed
ns secondary err code: 0
nt main err code: 0
nt secondary err code: 0
nt OS err code: 0
In the listener.log I see:
21-FEB-2006 16:38:41 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=HOMEDB)(CID=(PROGRAM=C:\oracle\ora90\bin\sqlplusw.exe)(HOST=ASPIRE3000)(USER=dsandu))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.14.101.51)(PORT=1605)) * establish * HOMEDB * 12500
TNS-12500: TNS:listener failed to start a dedicated server process
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 2: No such file or directory
My listener.ora looks like this:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = aspire3000)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = c:\oracle\ora90)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = HOMEDB)
(ORACLE_HOME = c:\oracle\ora90)
(SID_NAME = HOMEDB)
TRACE_LEVEL_LISTENER = ADMIN
What's wrong?
If I shut down the PC, restart the PC, restart Oracle services (listener and db) I can connect using sqlplus. If I shutdown down the database it won't restart.
Thank you very much for the help!

hi,
take another look at your listener.ora file, esp this line:
(ADDRESS = (PROTOCOL = TCP)(HOST = HOST = aspire3000)(PORT = 1521))
... perhaps a typo.
here is my file:
# LISTENER.ORA Network Configuration File: C:\oracle\ora92\network\admin\listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = ORADELL)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oracle\ora92)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = ora920)
(ORACLE_HOME = C:\oracle\ora92)
(SID_NAME = ora920)
