hi tom: I’ve updated the svn to 2903, it had in 2894. I understand that your recommendation is to add a fog hosts trought pxe. If there is no other solution will be what I will do. My idea is this: On a computer with fog service if the detected mac not found in the database, which makes equipment inventory and automatically add it to fog. I am studying the MOD_HostRegistrer.cs file for editing and allow to add this information. I do not know if what I have thought it can be done, or perhaps is already done and I can not make it work. Thanks for all :)
