That's the can of worms I opened. I started what I thought was going to 
be a simple task, and ended up replacing my win2k domaincontroller. It 
is a 1024 subnet and 700 + users and did it 2 weeks before school 
started. Sweat pumps were in high speed. I must say that my problems 
have been fewer and log in times greatly reduced. I checked into fds 
then but just couldn't seem to grasp it. I tried all the windows to 
linux authing and storage, could get the authing easy enough, but the 
storage thing just didn't come, over my head at this point, maybe next 
year I will understand it better. Nothing ventured, nothing 
gained.....of course, many a rabbit don't make it across the road.
