Disk utilization

You can use Performance Monitor. Select a Chart veiw. and then go to options and select Histogram. Where it says vertical limit put the most size each could be (ie 30000 = 30 Gigs) Then select add, Then Select LogicDisk, Scroll down the counters andselect Free Megabytes, Where it says instances choose what you want. All or indivual Drives. That should show you bar graphs of how much space you have left.

There are many ways to solve this problem:
1. Microsoft SMS
2. NetIQ Appmanager
3. Install and enable SNMP Service, Set-up an NMS and install Microsoft's MIB on the NMS to interrogate NT disk high watermarks.

For a machine population of 7500 spanning multiple domains the solution is not easy.

In my opinion there are two goods products, for it. First you can install SMS for Microsoft, its an excellent product that will offer to you more than check space in disk on the domain, you can do remote control of the machines, check all the resouerces of the machines in the domain, and keep all the information in an SQL database. Second you have a product no so expensive, this is Quota manager, that permits, to you adminitering the space in the disks and limit this. Its a good product, in windows 2000 it came incorporated.
Hope it helps you.

Try downloading the freeware util Freespace 1.0 from download.com.
It returns the free space and could be put in the login script and redirected to a file with the computer name.
Simple and quick but it works.
