Abstract: Described is an IT network (1) comprising distributed managers (2) and agents (3) which are arranged hierarchically in correspondence with an underlying likewise hierarchically arranged IT environment. Further a distributed database (5), or respective parts thereof, is provided for each manager (2) for storing information (6) about the configuration of the IT devices (4). For each IT device (4), an agent (3) is provided for retrieving the configuration information (6) for that IT device (4) from the database (5). The managers (2) and agents (3) use the computing power of the entire managed IT environment, whereby the managers (2) are implemented on IT servers (7) and the agents (3) are implemented on their corresponding IT devices (4). The agents (3) comprise intelligent behaviour insofar as they determine any necessary changes in the configuration of an IT device (4) being arranged at the same network hierarchy level or below that level independently on their own.
