Hi Raj,
Which version of weblogic are you using? Try to delete the cache directory of the managed server and try to restart it again and see if the problem goes away.
From Weblogic 9 version onwards by default when Managed server starts for the first time it will read boot.properties file inside domain directory and makes a copy of it inside its cache directory domain/servers/ManagedServername/Security folder. I think boot.properties file inside cache directory of managed server might be using old credentials.
The best way is to delete cache directory of managed server inside domain/servers you will see directory by managed server name, delete it and restart the managed server.
Hope this helps!!
