What does:

c:\TNSPING SERVER

have to do with:

c:\sqlplus connect scott/tiger@orcl

They would presumably be different databases.

What have you got in your tnsnames.ora for orcl?
What does:

c:\TNSPING orcl

give?

1/ Check your Oracle releated services in windows. If it's stopped then start.

2/ Set your ORACLE_SID

3/ Try to connect

You can using SID instead SERVICE_NAME in TNSNAMES.ORA
Or
You add GLOBAL_DBNAME=orcl in LISTENER.ORA

Good luck
