Windows could not start DBConsole for new database instance

Question

Hi,
I am getting this error "Windows could not start the OracleDBConsoleOracleInstance2 on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the system vendor, and refer to service-specific error code 1".
I installed Oracle 11g on Windows 7 and created my 1st database instance (oracleInstance1) successfully with a listener and service configured. I could access this database using DBconsole URL: https://hostname:1158/em.
I see the services started for:
OracleDBConsoleOracleInstance1
OracleOraDb11g_home1TNSListener
OracleServiceOracleInstance1
Next, I created a second database instance (oracleInstance2) and have configured a new service for this database. I am using the same listener as I intend to use one database instance at any point of time.
However, I got this warning message during configuration:
"Enterprise manager configuration succeeded with the following warning - Error starting Database Control. Please execute the following command(s).
1. Set the environment variable ORACLE_UNQNAME to Database unique name.
2. C:\Oracle\product\11.2.0\dbhome_1\bin\emctl.bat start dbconsole"
To start the new database console, I stopped the previously running DBConsole, OracleDBConsoleOracle1 and started the new DBConsole OracleDBConsoleOracle2 and get the above error.
When I try to start dbconsole manually using "emctl dbconsole start", it starts OracleDBConsoleOracle1 instead.
I changed environment variables ORACLE_SID=oracle2 and ORACLE_UNQNAME=oracle2
What am I missing here. Please help!
Thank you.

Why?
and started the new DBConsole OracleDBConsoleOracle2 and get the above error.

What am I missing here. Please help!First thing you are missing is showing us what you did. Instead you just described it, and that leaves a lot of room for questions. Copy and paste from a command prompt can work wonders here.
From a command prompt, enter the following:
set ORACLE_SID=oracle2
set ORACLE_UNQNAME=oracle2
set | sort
net start
emctl start dbconsolecopy the entire session, commands and full responses, and paste back here.

Thank you.Just to take a side road ...
"I am using the same listener as I intend to use one database instance at any point of time. "
Doesn't' matter if you use one instance or 100. The listener was DESIGNED to service multiple instances of multiple versions running from multiple homes. It is nothing but a connection broker. A telephone switchboard, if you will. All you need is a single listener, with the default name of LISTENER, running on the default port of 1521. It will handle all the database instances you care to throw at it. More instances than anyone in their right mind would ever put on a single server. Your server will run out of capacity to host additional instances before the listener runs out of capacity to service them. Especially since your 'server' is really just a toy in the Oracle world.
