Error connection Oracle to SQL Server using tg4msql, HELP Please....

Question

Hi, my name is Gregory,
I am a newbie in oracle forum here, and need some help from the database guru here...
I am trying to create the database link from Oracle database to SQL Server.
here are the information:
host name of OracleDB = a3500
host name/Ip of SQL Server = 172.16.1.58
SQL Server database name = CKS_VSSD
i had create the new initntchsql.ora file under tg4msql\admin folder, and i also had create the new listener.
here is the file contains
############ initntchsql.ora ###################
HS_FDS_CONNECT_INFO="SERVER=172.16.1.58;DATABASE=CKS_VSSD"
HS_FDS_TRACE_LEVEL=OFF

and i had created databaselink named ntchsql
then i select statement:
select * from vssd50@ntchsql
and error occured:
ORA-02068: Following severe error from NTCHSQL
ORA-28511: lost RPC connection to heterogenous remote agent using SID=%s
ORA-28509: unable to establish a connection to non-Oracle system
did i missed something on the configuration?
oya... i also see other thread that said i have to comment
SQLNET.AUTHENTICATION_SERVICES = (NTS)
from sqlnet.ora file, and i did that, and the error still the same...
can somebody help me?
