I checked that Oracle and Listner Services are Running and SET to Manual.
And the Local User is the Member of ORACLE_DBA Group.
all the files listener.ora, sqlnet.ora, and tnsnames.ora are available in the Same directory.
and the RAM is Now 512 MB. But Still the Same position.
Here are Files.

(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
LISTENER =

(ADDRESS = (PROTOCOL = TCP)(HOST = assist_nadmin.KSM.KAMAL.COM)(PORT = 1521))
DEFAULT_SERVICE_LISTENER = (XE)

SQLNET.ORA

# This file is actually generated by netca. But if customers choose to
