Quick question, this is theoertical by the way.

If i had 3 departments for a businesss:
* Human Resources
* Finance
* Marketing

If i had a total of 300GB of space on the netrwork, how could i allocate 100GB to each department, and ensure that one department cant go over that 100GB limit.

I assume i would need to use disk quota-ering in windows server?

Any more of an idea would be good


Yes, you can use windows server's quota tool. There are 3rd party applications that provide additional more detailed quota features.

Is there some you could mention, so that i could look into them

Spaceguard is one that I've had interaction with.
