(Oracle 10g / windows)
Althouth the net configuration assistant passes a connection test to a given TNSname, any other application throws this error message:
Checking sqlnet.ora and tnsnames.ora doesn't reveal any errors, although almost all knowledge base entries point out that this ORA-12154 is a result of a misconfiguration within one of those files.ORA-12154: TNS:could not resolve the connect identifier specified
[SOLUTION]
If you've installed an oracle client on that machine.... REBOOT IT!
And then try again. Hey! It's windows!
