Hello everyone;
I apologize if this problem has been discussed already but I am really a beginner and my problem has persisted for a long time:
My database is oracle 10g I created (the database was really created by default during installation) a base whose SID is "orcl". She is on a remote database server data (Windows). I checked the file tnsnames. ora file listener.ora file sql.ora but the connection does not work with oracle sql I develop on my machine oracle client is installed. is there any recommendations to check a file changes ...
Thank you it is very urgent

Check if your server is on.

Seriously, do you think we can know what is wrong without having any information?
What is your error?
What do you see?

ok my friend You Have Reason. I described the condition: I work with a pc in which Oracle client(10g) is installed, operating system windows xp sp2 . the oracle server is installed on a server remote database with the operating system is Windows Server 2008. this server belongs to a domain. I try to connect to the Oracle database located on the server. For this I made 2 methods:
1 - I try to connect to oracle using oracle sql developer but even by providing the connection parameters login password username, SID,IP there is an error message: "Exception I / O: the network adapter could not establish the connection "
2-I tried to get connected through a vb.net application that I used to connect to a local oracle database here is the error message: "ORA-12170:
TNS: Connect timeout occurred "

Here is my problem. is that there's other information I have provided?
Note well: I tried to connect from a PC in the same domain and another not belonging but the same problem.
Thank you.

From WINDOWS database server system CUT commands below & PASTE into terminal window:

type %ORACLE_HOME%\network\admin\listener.ora
type %ORACLE_HOME%\network\admin\tnsnames.ora
lsnrctl status
lsnrctl service
/ as sysdba
select * from v$version;

CUT results from commands above & PASTE all back here

CUT & PASTE from command line on database server showing that you can successfully connect to instance on DB Server via SQL*Net
