Oracle 8i to SQL Server by Gateway

Question

Trying to setup a Transparent Gateway between Oracle 8.1.7 using Gateway 8.1.6 to MS SQL Server.
Tried Gateway on both NT and 2000 Server.
Here is the Error Message:
SQL Plus Error Message

Any suggestions?
Here are all the *.ora files.

I am a new member for OTN. I am facing a problem while connecting msassess database with oracle 9.2.0 with the help of hetrogeneous connectivity feature.
I have done all the needful as suggested by many members in this forum. but finally when accessing a assess table with the help of the link , get the error "ORA-12154: TNS:could not resolve service name "
I have checked all relevant entries in sqlnet.ora,hssid.ora,tnsnames.ora and listener.ora.. also created ODBC dsn. but couldn't resolve my problem.
listener is regestering the service. but when tried tnsping . this utility shows following message and keeps on trying to contact: "
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = tcp)(HOST = bsesxx)(PORT = 1521)))"..................
but not connect_data string. perhaps this is the cause of whole mess.
I am posting contents of all relevant files.
Oblized if anybody could help me as for last 2 days I ahve been storming my brain but no success.
