Cannot connect to local Oracle11g manually?

Question

Dear,
I installed Oracle 11g on WinXP SP2 machine using localhost with only 1 database SID="EBIZ". There are 2 services called OracleOraDb11g_home1TNSListener and OracleServiceEBIZ. By default, these services have startup type as Automatic, and I can connect my database ebiz easily (i.e. using SQLDeveloper to connect & access the db).
The problem is that I do not always use Oracle so I start these 2 Oracle services manually by setting the startup type as Manual and start them when necessary. However, doing this way, I receive an error "ORA-12505: TNS:listener does not currently know of SID given in connect description". Specifically, the database instance EBIZ cannot register to the listerner because when checking listener status (by cmd lsnrctl status) it says "The listener supports no services".
My steps to start 2 Oracle services are
1. Start OracleOraDb11g_home1TNSListener
...Wait several minutes to ensure the listerner works...
2. Start OracleServiceEBIZ
... Wait several minutes to ensure ???
But the result of cmd lsnrctl status is:
