What to do after 11g R2 install on win 2008, get errs trying to start dbcon

Question

The install run fine, but at the end it gives you a nasty warning saying the following:
1) Set your environment Variable ORACLE_UNQNAME to the Database unique name"
2) c:\app\oracle\product\11.2.0\dbhome_1\bin\emctl.bat start dbconsole.
Why id didnt do this for you as part of the install I dont know. Anyway, I set a SYSTEM environment varibale ORACLE_UNQNAME ot orcl (I have no idea what Database unique name is, but Im guessing its either the SID or the Gloabl DB name. i have tried both, and neither seem to work).
After this, I fire up powrer shell, and enter:
c:\app\oracle\product\11.2.0\dbhome_1\bin\emctl.bat start dbconsole
which give the error:
- An instance of Oracle Enterprise Manager 11g Database Control is already running.
So I try this:
c:\app\oracle\product\11.2.0\dbhome_1\bin\emctl.bat stop dbconsole
which gives the error message:
The OracleDBConsoleorcl service is not started.
More help is available by typing NET HELPMSG 3521.
I try starting it again, and its says its already running.
WTH?
After installation, how does one get oracle working?
Looking at services, I see that OracleDBConsoleorcl is stopped. If I try and start it as a server, about 20 secons later it stops again.
Any ideas?
Does one have to set any other environtment variables, and what should they be?
If I try and login to the em console on 1158, it says
Internal Error has occurred. Check the log file for details.
Unfortuatnely, it doesnt say what log files or where they are. if I got to the sysman/log dir, there is nothing there.
This is the 3rd attempt to install oracle, wasting some 3 days so far. The installer just doesnt work.
Has anone ever got 11g R2 to work poperly on windows serer 2008?
Right after the install, the DB and listener are up, I can connect to it via sqlplus or toad. However, As soon as I reboot the machine, from experience, I know the listener service will no longer start, and there will be no errors in any logs.
Thanks for any help.
Ive tried installing enterprise and standard edition - both fail in the same way. Ive tried installing as custom users in the Administrators group, and installing as Administrator. Both fail in the same way.

Im not expecting any help, but I will document the pain just in case anyone from oracle read these forums.
Having done the install with no errors, as said, the em console just doesnt work.
Next problem is I cant even use sqlplus correctly. If I do this (as the user who installed oracle):
sqlplus / as sysdba
It gives:
ERROR:
ORA-12560: TNS:protocol adapter error
So I cant even start/stop the DB.
Im contemplating my options here. one is to switch back to Unix, and try installing oracle on that. The other is to port our entire app to mysql. Im not sure which is the quicker approach.
"Switch back" to unix? Why would you ever have "downgraded" from unix to Windows in the first place? What's the cost of license and annual support for Oracle Linux vs. Windows?
I avoid Windows every chance I get. Not because of the specific issue you are having (which actually is probably something rather simple), but simply because Windows is such a miserable excuse for a serve OS. I've always had Oracle on both nix and Windows in every shop I've worked as an Oracle dba.  In fact, my first oracle db's (ver 7.3) were on Windows.  I consider myself equally adept in both environments, but I still find nix far easier to work with as a server OS.
There are no logs in sysman/logs
