Unable to reset WAS admin password. unable to login WAS console

I am unable to login inot WAS Admin console. So I am trying to reset the admin credential after disabling security(security.xml-enabled="false"), but unable to save the new password. Any idea what should I check and troubleshoot?

I tried entering the credentials on soap.clients.props, but no help. WAS version : 7.0

The credentials that you entered do they exist in the WIM registry?

From the screen shot it appears that you are using the File Based registry. Check that the ID and passwords match the values in that File Registry.
