Disk Quota in windows
Disk quotas were introduced in Windows 2000, and are applied to specific users and limit the amount of disk space that user can use on a particular volume.
Windows 2000 disk quotas track and control disk storage usage on a per-user, per-volume basis. Windows 2000 tracks disk quotas for each volume, even if the volumes are on the same hard disk.
Directory quotas are applied to all users and limit the amount of disk space that users can use in a particular folder and its subfolders. Directory quotas were introduced in Windows Server 2003 R2 with the new File Server Resource Manager.
Note : You need NTFS volume for setting Quotas

Configure and use disk quota in 2003
In Windows Server 2003 R2, just as in Windows Small Business Server 2003, the fsutil command provides a quick shortcut to quickly changing a specific user’s disk quota limits and warning levels.
Traditional Windows disk quotas are calculated using files’ logical size and are based on the user owning a file, not necessarily the user maintaining or storing the file.Windows Server 2003 R2 also includes a new feature that addresses several disk quota issues that is called File Server Resource Manager(FSRM).
Using Group policy
Open the Group Policy Object Editor (gpedit.msc) and navigate to Computer Configuration > Administrative Templates > System > Disk Quotas > Enable
you can select 3 settings there
Allow processing across a slow network connection

After the file server role is installed
Server Manager > Features > Add Features > Remote Server Administration Tools Role Administration Tools > File Services Tools > File Server Resource Manager Tools. Select the File Server Resource Manager Tools check box, and then click the Install button.
