Thanks all
I'v been writing kix for years, and still I dident know that there was an builtin function called Logoff() !!! Thanks Les.
Shawn, your idee about limit in the router is good, but I dont want them to logon and start games...
I shall look into that software Enuff, but probably that is only in English. I want it in Swedish. My girl is only 7 years and dont understand so much English.
I have a windows domain at home so I can use domain logins where i can put my script. So even if they are local admins they cant get past that login script.

Well, I shall do a test, and will be back with some kind of result.
