I have installed Oracle 10g on my pc. Now, when I try to login in with Scott/Tiger, system/manager or the Database username/password given while installing Oracle 10g, it gives me "ORA-12560 TNS Protocol Adaptor Error". I tried the solution mentioned here to start all Oracle Services and all the services are started, still I can't login. Please help.

Hello, there's too little information to help you. Is your listener running? How is it configured? Is the database actually running (check the alert log)? Is the database registered with the listener? Is your environment set up correctly (ORACLE_HOME, _SID)? – Mat Jan 28 at 11:15
