I think I may have solved the multiple login problem with users (on NT4 systems)
I look after a school network of anywhere up to 250 users using the system at any point in time, real headache when I disable a user, and they 'borrow' someone elses account.
I had a friend write me a program that runs in the background and writes to the users home share (G:) to a hidden file called "semaphore.dat". The program deletes this file every 5 mins and recreates it, and upon logoff it deletes it totally.
Theory is, that if a 2nd user logs in, I want kixstart to check the file time and if less than 5 mins old then log the 2nd back user out. and if older than 6 mins (1 min margin of error) , then delete and allow the login - this way if a computer crashes and restarts there is only a 5 min wait before the user can log in again (since the semaphore file will still exist).
Now I'm hoping that someone can help, and I manage to pull this off.
I figured uing 'getfiletime' would be the way, but I'm stumped on how to check the age of it. Can anyone help with this? (I'm still a kixstart newbie)
Also - if it does work - is it worth posting the program somewhere for others to use it?
Any help appreciated.

didn't suprisingly find any udf, which would do that, so made my own.
it does not handle day change at all.
code:
$file=right(getfiletime("testi.txt"),8)
$time=@time
? "$file - $time"
$file=3600*val(left($file,2))+60*val(substr($file,4,2))+val(right($file,2))
$time=3600*val(left($time,2))+60*val(substr($time,4,2))+val(right($time,2))
$fileage=$time-$file
"file age in seconds:"
?$fileage
if $fileage>300
?"so, it's older than 5 minutes..."
else
? "it's pretty fresh file, less than 5 minutes."
endif
hope it helps

It worked!
had to upgrade my Kixstart and rest of my scripts (I think it was version 3.0-something before - which caused a few weird things like printers not behaving)
But everything seems happy now. Students are now restricted to one logon at at time, and in the event of a computer crash, they are locked out for 5 mins (I think I might reduce this to 2 mins)
Thanks for the help!
much appreciated.
