Which ODBC driver?  If it's the Oracle provided driver, it's on the Client CD.  If you don't have a copy of the software and the version you want is still supported, you can download it from:

If you are using the Microsoft ODBC driver for Oracle, you'll need to get that from the microsoft site.
did you check TNSListener on the server side?

I agree with cdemir.  It's probably a listener problem but it could also be a Firewall issue.  Are you receiving any error messages?

On the DB server execute: lsnrctl stat
On the client side execute: tnsping <DB NAME>
where <DB NAME> is the service name you provided in the DSN setup.

I'm trying to enter with Oracle enterprise manager, as system manager and I can´t reach too
i have this message " ORA-1254 TNS: Could not resolve service name"

Since you say this suddenly happened:  What changed?

This error means there's a problem with the entry in the tnsnames.ora file on the client.  The full text about this error is a little lengthy so here's the link for it:
