Access to shared files on remote PC from application deployed on TC server

I have deployed my application on TC server. When I start TC server as a service, it is not able to read shared files on remote PC. When I deploy the same application on tomcat and start tomcat using "startup.bat", it is accessing shared files on remote PC. Is there any configuration required to be done when TC server is started as a service? Any settings need to be done for TC server so that it will get access to shared files on remote PC?My objective is to deploy my application on TC server and to access shared files on remote PC.
