Listner issues in Oracle 11g server installation

Question

Hi,
I am facing problem while connecting to Oracle 11g server on 'Windows 7 Enterprise edition - 32 bit OS'.
I have successfully installed Oracle 11g server on Windows & enterprise machine.
Listener and TNSnames.ora files are fine. But I am not able to connect through Oracle client machine. it shows 'TNS: Could not resolve the service name'.
When I check the listener status on the server, it shows the service ABBPROD is READY, but still not able to connect through client machine. I have gone through many similar threads and tried out the solutions provided but the problem still exists. Few of the things I tried are as below.
1. I have tried changing the ORACLE_SID and setting the $ORACLE_HOME parameter.
2. Tried replacing the HOST as 'localhost' to system IP address/computer name
3. Listener stop and start
4. Service stop and start
5. Checked the firewall settings of the server machine
I shall paste the listener.ora and tnsnames.ora files below.

I checked the global_name, it is ABBPROD.asiapacific.abb.com...
I tried setting the ORACLE_SID same as this name, but still the same issue exists
@Mahir, this is a production environment, and I cannot take risk of rebuilding tnsnames and listener.ora filesand
