Method for incorporating a communication device (T1, T2,... TN) in a network - having a set of configuration servers (KS1, KS2,... KSj) having at least two configuration servers (KS1, KS2,... KSj), and - having a set of productive servers (PS1, PS2,... PSi) having at least two productive servers (PS1, PS2,... PSi), having the following steps of: a) establishing a connection between the communication device (T1, T2,... TN) and the network via a network access component, wherein the network access component forwards data coming from the communication device (T1, T2,... TN) to a network filter component, wherein the network filter component first of all forwards the data solely to a stipulated selection from the set of configuration servers (KS1, KS2,... KSj); b) obtaining configuration data from the stipulated selection of configuration servers (KS1, KS2,... KSj), which data stipulate access rights of the communication device (T1, T2,... TN) to a selection from the set of productive servers (PS1, PS2,... PSi); c) configuring the communication device (T1, T2,... TN) and the network filter component using the configuration data which have been obtained in such a manner that access of the communication device (T1, T2,... TN) is restricted to the selection from the set of productive servers (PS1, PS2,... PSi). - having a set of configuration servers (KS1, KS2,...
