Problem with Listener in Oracle RAC 11.2.0

[Big George]

Hello
I've got a problem with listener

O/S: Windows Server 2008
Database: Oracle RAC 11.2.0
Number of Nodes: 2
Storage: ASM

Node A does not connect to ASM. However Node B does and database is
up.
In NodeB, I can connect to database via sqlplus. No problem.

Problem is that clients can't connect to database because of this
problem: ORA-12541: TNS No listener

In Node B, if I try to start listener I got:
------------------------------
C:\>lsnrctl stat

LSNRCTL for 64-bit Windows: Version 11.2.0.2.0 - Production on 20-

Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
64-bit Windows Error: 61: Unknown error

C:\>lsnrctl start

Starting tnslsnr: please wait...

TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error

------------------------------

What should I do? Recreate listener? I would prefer to just modify
file:
C:\app\11.2.0\grid\NETWORK\ADMIN\listener.ora
If something goes wrong, I can have a backup.

If I change in file listener.ora of Node B, should I made the same
changes in Node A?

A) In RAC environment you shouldn't be starting listener with lsnrctl, it
goes to $ORACLE_HOME instead of $GRID_HOME. Most likely, you don't even
have $ORACLE_HOME/network/admin/listener.ora. You should start
listener by issuing the following command:

srvctl start listener -n <node name>

B) Check the log file. There is a utility called "adrci" and you can use
it like this:

[oracle@medo ~]$ adrci

The "show problem" command should tell you whether you have a problem.
For the particular occurrence, you can check "show incident" command.
Here is a great tutorial for the ADRCI utility:
