I can not start RAC instances of Oracle RAC database

Hi Experts,
I have a big problem. Recently we have taken a responsibility of a new system which db is oracle 10g and RAC is configured (Windows 2003 Servers). But when I execute i see that nodes status are  not running. But instances are up and i can connect them within sqlplus.

C:\oracle\product\crs\bin>srvctl status database -d vis
Instance vis1 is not running on node kdbsrv1
Instance vis2 is not running on node kdbsrv2

when I run srvctl start the output is like below,

C:\oracle\product\crs\bin>srvctl start database -d vis
PRKP-1001 : Error starting instance vis1 on node kdbsrv1
CRS-0215: ora.VIS.vis1.inst source could not started.
PRKP-1001 : Error starting instance vis2 on node kdbsrv2
CRS-0215: ora.VIS.vis2.inst source could not started

I did lots of thing.
srvctl remove instance / add instance (nothing changed)
srvctl modify database -p <SPFILE>-s open (nothing changed)
srvctl stop / start database .. many times but no help

can you please share your experiences with me. I am not expert on RAC serives but i must bring it online asap..

Thanks in advance for your supports

crs_stat -t output was like this.

Ok. I solved problem.

When we got the system from other company, we have changed sys password. After that time we couldnt login " sqlplus  / as sysdba" .  That was because the pwd<instance>.ora was invalid. To solve this, I have changed Authentication type from None to NTS in sqlnet.ora . And in Active Directory Users and Computers added the db servers in to pre-windows 2000 authentication group from member of section of properties page.
then I could login as / as sysdba.

you can see thet crs services connect instances with out password (/ as sysdba)
type crs_stat -p then you will see the detailed info on crs applications.

So, I am closing the question
