11g R2(11.2.0.2)-Not able to connect using SID - Win 7 32 bit

Question

Hi Experts,
I have installed 11gR2(11.2.0.2) on Win 7 32 bit OS.
I am able to start database and listener services without any problem. ORACLE_BASE and ORACLE_HOME variables are set.
I am even able to connect to database using "sqlplus user/pass". (With ORACLE_SID variable set)
However, sqlplus command hangs when I try to connect using SID "sqlplus user/pass@o11gr2".
(No error, after waiting for >20 minutes I have to kill the command.)
=================
Following in "C:\Oracle\product\11.2.0.2\dbhome_3\RDBMS\trace\o11gr2_ora_6352.trc"
- "2012-04-05 09:50:55.846: [ default]ut_read_reg:2:ocr registry key SOFTWARE\Oracle\ocr cannot be opened. error 2"

The command completed successfully
=================
This was working earlier. One day it stopped working all of a suddent and I am not able to connect using SID till now.
I tried re-installing in different home multiple times. But no luck even after disabling firewall completely.
Any suggest/help is greatly appreciated on this.
