To make a long story short -- we change passwords on the sys, system and about 4 other accounts that we have in our Oracle 10g DB. I changed the password on all of the accounts (had to include "" around the password), but now I'm unable to log on with any of them due to an incorrect password or ID. I'm basically looking for any other option to log onto the db via sqlplus and change the sys password without logging in.
What I've already done:
checked to make sure my domain account is in the ora_dba group
altered the sqlnet.authentication_services = (NTS)
already tried to logon with sqlplus / as sysdba (ORA-01031: insufficient privileges.) even with sqlplus /nolog
I haven't tried deleting the pwd file -- didn't look as if it would've made a difference for me....
Is there any type of back door when unlocking the sys account?
can I restore the db from an RMAN backup to reset the password?
Any help would be greatly appreciated.

I would log on to Windows as a local user (not with a domain account) who is in the ORA_DBA group, and then try Please can you show (with copy/paste) what happens happens when you do. Also, show what happens when you try to connect as another user, such as SYSTEM.

OK, your IP address does suggest that you need to be careful.
The output of WHOAMI is not right. I think each group should be prefixed with the name of the machine, for instance. Is what you have transcribed what you actually see?
One suggestion: set some environment variables explicitly before attempting to connect, like this:
c:\users\john>
c:\users\john>set ORACLE_HOME=c:\app\oracle\product\12.1.0\dbhome_1
c:\users\john>set PATH=%ORACLE_HOME%\bin;%PATH%
c:\users\john>set ORACLE_SID=orclz
c:\users\john>sqlplus / as sysdba

You have still not shown how you attempted to log on a SYSTEM. Can you provide the exact command?

Well, the whoami output looks fine. If your environment variables are right and your OS permissions are right and NTS is enabled in your sqlnet.ora and the service is running under a local system account (it is, isn't it?) then it should work.
The only remaining suggestion I have is to delete the Windows service for the instance, and create a new one (use the oradim.exe utility for this). Failing that, install a new Oracle Home and use that to create a service and open the database.
Perhaps someone else has an idea.
