I am trying to set up a stand by environment in Windows Environment with Oracle 11g

Hi,

I am getting the error 
Error 1033 received logging on to the standby
PING[ARC1]: Heartbeat failed to connect to standby 'to_standby'. Error is 1033.

Please help

When I checked I am unable to connect the stand by server from primary and Vise versa. But I can do tns ping
I have password file in both servers

 Standby is mounted and all the services are started and Up
