aii.properties not loading in NW CE 7.1

I have placed aii.properties file under cluster/server0,but it seems not loading the properties from this file to server.

Environment: Stand alone, NW CE 7.1, configured to PCK. Most of the functionality is working fine, except which relays on aii.properties file. What could be the reason that server is not loading aii.properties?

Can any one suggest?
