11g Client Config/Net Config Error

Question

Local Net Service Name configuration: Connecting...ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
The test did not succeed.
I can log in to the ORCL database with SQL*Plus from the database application and the client application if I use: connect scott/tiger. If I try to use connect scott/tiger@orcl, I get this error: ORA-12514 TNS:Listener does not currently know of service requrested in connect descriptor.
64-bit Vista Ultimate
Oracle 11g with loopback adapter
Thanks,
Donna
