You'are right, I think I have to disable the KTD option for end user, but it's very useful (KTD) when you want to set up a Test machine wich will like everything you gave it something to eat :-)
By the way, I have seen the reply of roguespear where he gave me a link to his script ( sorry I really wouldn't to steal the idea, I haven't even search before... shame on me!)
His script seems very advanced compared to my poor one, I need to read more about his work, but at this time, my simple sricpt is enough for my use, I just wanted to share with you my work ,
So if you need a simple scirpt take this one, if will ask you or not for DP then for KTD, i think I shall put a timeout on each, it could be good to have some help about that... a timeout choice in CMD, how make we that???
If we can set up a time choice, maybe overflow will like it though!!! :):) ( because a timeout doesn't break automation, so the "pause" fonction is invalid for us...)
See you soon.
