(57) ABSTRACT
The invention provides a method and system of detecting aliases in a network. The network comprises at least one device and at least one Network management system (NMS) for managing the devices. The NMS identifies each device available in the network with a message digest. The NMS retrieves the message digest of a device that is submitted for management. The NMS tries to locate the retrieved message digest with a database of message digests. In case the retrieved message digest is located on the database, the NMS declares the device as an alias. However, if the message digest is not located on the database, the NMS stores the message digest in the database and starts managing the device.
