It looks like yor are using Oracle on Windows , you can recreate password file by using orapwd utility. The location of password file is in ORACLE_HOME/dbs

C:\>orapwd
Usage: orapwd file= password= entries=

where
file - name of password file (mand),
password - password for SYS and INTERNAL (mand),
entries - maximum number of distinct DBA and OPERs (opt),
There are no spaces around the equal-to (=) character.


The other thing is what is try setting REMOTE_LOGIN_PASSWORDFILE = NONE
in your init.ora parameter file.
