Thx it works!

When I look in cmd with net use command and I have connected to I: it says connected. When I then use

USE I: /del

and then type net use, it says I: not availble, and I cant see it under my computer. If I then try to use

USE I: /Del /Persistent

It dissapear totaly from net use view. Thats good. The strange is, even if I use

USE I: \\server\share /Persistent:no
USE I: /del

It says not available when I type net use. Doesn't Persistent:no works with kix, I think I have read i should?
