Hi, sorry I have not read everythink but the problem do you have is , if I understood everythink correct:
1) server machine has OS unix
2) client machin has OS Windows
NEVER apply configuration files from UNIX to WINDOWs and forward as they have absolutly different coding, you can't see all characters in your file but they are here, for example you cant see chr(0), chr(10), chr(13).
So solution is: remove tnsnames.ora from your client and create new one. Using Windows tools or manualy, I had the same problem .
Best wishes.

Gurus,
i have set up my listener at client side and tnsnames.ora at client side. I am using oracle 8.1.5. Clients are installed on the client machines. When i try to connect on the server with the same instructions in tnsnames.ora as in client side, it connects. But from the client's machine, it refuses...
Please Advice...
Thanks,
Mohit.
