Need help setting up DB Link from my Oracle 11g XE to SQL Server.

Question

Hi,
I'm trying to create a DB Link from my Oracle 11g Express Edition in a Windows XP machine to an SQL Server. Here are the steps I've done so far.
1. Created and setup an ODBC Connection for the SQL Server DB. Named it SQLSERVER. Windows Authenticated.
2. Modified listener.ora. See below.
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    (SID_DESC =
      (SID_NAME = SQLSERVER)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = hsodbc)
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
DEFAULT_SERVICE_LISTENER = (XE)3. Modified tnsnames.ora. See below.
XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
SQLSERVER =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT=1521))
    (CONNECT_DATA =
      (SID = SQLSERVER)
  (HS = OK)
)4. Copied C:\oraclexe\app\oracle\product\11.2.0\server\hs\admin\initdg4odbc.ora to C:\oraclexe\app\oracle\product\11.2.0\server\hs\admin\initSQLSERVER.ora and modified it. See below.
# This is a sample agent init file that contains the HS parameters that are
# needed for the Database Gateway for ODBC
# HS init parameters
HS_FDS_CONNECT_INFO = SQLSERVER
HS_FDS_TRACE_LEVEL = off
# Environment variables required for the non-Oracle system
#set <envvar>=<value>5. Restarted listener.

Here's more information on the machines.
Machine where the Oracle Database 11g Express Edition: IP Address is 10.162.128.67
Machine where the SQL Server database: IP Address is 142.120.51.30.
I've modified the tnsnames.ora to the following:
XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.162.128.67)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
SQLSERVER =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 142.120.51.30)(PORT=1433))
    (CONNECT_DATA =
      (SID = SQLSERVER)
  (HS = OK)
)But now I'm getting the following error:
