Hi ! Forgive me for my awful english...I'm french (nobody is perfect). I'm trying to collect many informations on web sites (french or not) to make an unattend installation of my xp with sp2. I've seen on many forum topics, in the section [components], a line: msmsgs= off, to disable windows messenger. But when i search this line in the ref.chm help provided with the deployment tools i do not find it. I tried to find it also ine the ref. chm files provided with the XP original version and the XP SP1 version and i don't find anything about this. Is there some sections or entries not documented in ref. chm ? Another thing is not very clear for me: Is it possible to know if disabling an component in the winnt.sif file means the component will be installed BUT NOT enabled or not installed at all (for example for the firewall or for services i don't need). If someone is able to understand my english and bring me some light... Thanks.
