I have Mcafee Personal Firewall 2005 running, but I disabled it, too; however, I'm having the same problem.
This is the tnsnames.ora file: SNOOPY = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = neptune)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = Snoopy) ) ) EXTPROC_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC)) ) (CONNECT_DATA = (SID = PLSExtProc) (PRESENTATION = RO) ) ) This is the listener.ora file: SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = C:oracleproduct10.1.0Db_1) (PROGRAM = extproc) ) (SID_DESC = (GLOBAL_DBNAME = snoopy) (ORACLE_HOME = C:oracleproduct10.1.0Db_1) (SID_NAME = snoopy) ) ) LISTENER = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = neptune)(PORT = 1521)) ) This is the problem: Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp.

I've received the same TNS-12560 error starting the listener when I've been connected to the database server through Remote Desktop. The solution is to either connect to the database server directly or to start the Listener service with the following command:
net start OracleTNSListenerYou will have to look up the exact name of your Listener's service in Control Panel. My example uses the service name "OracleTNSListener."
