Hi everybody, I have promised you, nearly a year ago to explain my solution In order to prohibit Internet access under XP Home for certain sessions, the idea was to activate during startup the Internet connection and to disable it before extinguishing the computer or closing the session in progress for the users with high priviledges (administrator type under XP Home). Indeed the other users with lower priviledges, cannot activate the Internet access (by right clicking on the icon of connection then by choosing "activate") if this one is disabled before starting up. This icon remains grayed. To carry out these activations and disablings in an automatic way, it is necessary to be able to launch an executable during startup and another one before closing the session or switching off the computer, and this systematically. The execution of a script during startup does not cause any problem, it is enough to place a short cut in the starting directory pointing towards the script to execute. Nothing is foreseen on the other hand : 1/ To Execute a script before closing a session or switching off the computer under XP Home. My first idea was to look for the use of the Group Policy editor. Unfortunately Windows XP Home does not give access to this editor (gpedit.msc). Only Windows XP pro makes it possible to do it. Please see: Group Policy Editor explanations in English or Group Policy Editor explanations in French One finds well on the Net the possibility of installing this additional functionality on computers carrying out Windows XP Home, but the group policy editor remains inoperative in spite of appearances. At least for the functionality which consists in executing a logoff script. The user interface of the editor works well but not the functionality modified by means of this interface. I ended up discovering the work of a specialist (Mr. Alexander Frink) who wrote a freeware that I tested on my personal computer under XP Home service pack 2 allowing to execute a script at logoff of a session or before the extinction of the computer. Here are his explanations. This freeware "gina_x86.dll" is substituted to a native Windows librairy '* dll' named "msgina.dll". By modifying keys in the register data base, it is possible to execute logoff scripts under XP Home edition. Unfortunately it is necessary that the logoff script is located in a shared directory by all the users. It is a weak point on which I am thinking about. In any case I have crypted my logoff script while waiting better. Note that the logon script is protected because it is located in the starting directory of each user. This directory is distinct from one user to another and can be reached only by the user of the session in progress. Once the possibility given to XP Home to execute logoff scripts, it is now necessary to find the way: 2/ To activate and disable the internet connection without any manual intervention of the user by means of a script. Here also, I have taken advantage of exchanges of experts on a forum explaining a VB script doing what I was looking for. This Visual Basic script can be run under Windows XP (Home or Pro). It has to be duplicated in 2 files: one to enable the internet connection at startup, the other to disable it before login off or switching off your computer. These scripts have to be francized for those who have a French version of Windows XP ("En&able" = "Activer"; "Disa&ble" = "Désactiver"; "Network and Dial-up Connections" = "Connexion au réseau local" etc...). Hope this will help one of you
