Looking towards the complex, heterogeneous and dynamic nature of the networks, failures are unavoidable. Monitoring can be used for detection and reporting of failures. This underlines the need to develop a unified strategy for implementation and management of network resources in an enterprise.This paper describes novel agentless system for real-time monitoring of windows based clients remotely by subscribing to those remote events. Monitoring is done using W indows Management Instrumentation (W MI) services. Results of service events are stored in Server. This system is called as Unified network resourse management system. We have demonstrated the system's capabilities and the results that are obtained from the clients using W MI services. These results include system hardware configuration, software configuration in terms of OS details, applications installed etc. This information is very useful to the administrator for maintenance of failures in the networks. Any change at the client system details, will be notified automatically by the clients to the server, so that server will have real- time updated information. This updated information will be very helpful incase of crashing of the remote client. Using this collected data, crashed clients can be restored in very short period of time. Real time monitoring of the clients is necessary for the maintaining the health of an enterprise network.
