Oracle DB access through client

Hi,

I installed Oracle database 11g on Windows Server 2008 R2 Standard edition OS.
But I am not able to access the Oracle database from other machine through Oracle client.
Getting error like "ORA-12541: TNS:no listener".

But am able to connect to the database on the same machine. The listner is also running.

I am able to ping the machine but not able to tnsping the db due to the above error

Earlier It was mentioned that this is a firewall blocking the ports.

If I disable the firewall in the services also am getting the same problem. And to the machine itself I am not able to connect (take remote desktop).

Is there any otherway for this issue for the oracle client connectivity?

Thanks.

Did you configured the tnsnames.ora in the oracle client installed machine? if yes

can you give the o/p of tnsping <SID_name>

Yes. tnsnames.ora configured.

tnsping ABCD

gave the below output. But when I check in server machine listner is already started its showing.

Earlier when I installed oracle server, I got "TNS-12535: TNS:operation timed out"
and at that time it got resoved with "firewall disabling " on the server machine.

But this time when I intalled the same oracle server in another machine using same installation kit, I am getting "ORA-12541: TNS:no listener".
But this time also tried with firewall disabling but could not be able to connect to database through oracle client.

Thanks.
