You can use any of the VBScript programs below in ActiveXperts Network Monitor. Click here for an explanation about how to include scripts in ActiveXperts Network Monitor.


Add a Disk Quota Entry on the Local Computer


Creates a custom disk quota entry for a user named kenmyer. This script must be run on the local computer. 
Set colDiskQuotas = CreateObject("Microsoft.DiskQuota.1")

colDiskQuotas.Initialize "C:\", True
Set objUser = colDiskQuotas.AddUser("kenmyer")
Set objUser = colDiskQuotas.FindUser("kenmyer")
objUser.QuotaLimit = 50000000

Create a New Quota Entry


Creates a new disk quota entry for the user fabrikam\bob. 
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2"

Set objAccount = objWMIService.Get _
    ("Win32_Account.Domain='fabrikam',Name='bob'")
Set objDisk = objWMIService.Get _
    ("Win32_LogicalDisk.DeviceID='C:'")
Set objQuota = objWMIService.Get _
    ("Win32_DiskQuota").SpawnInstance_

objQuota.QuotaVolume = objDisk.Path_.RelPath
objQuota.User = objAccount.Path_.RelPath
objQuota.Limit = 10485760
objQuota.WarningLimit = 8388608
objQuota.Put_

Delete a Disk Quota Entry on the Local Computer


Deletes the disk quota entry for a user named kenmyer. This script must be run on the local computer. 
Set colDiskQuotas = CreateObject("Microsoft.DiskQuota.1")

colDiskQuotas.Initialize "C:\", True
set objUser = colDiskQuotas.FindUser("kenmyer")
colDiskQuotas.DeleteUser(objUser)

Delete an Existing Quota Entry


Deletes a disk quota entry for the user fabrikam\bob. 
strDrive = "C:"
strDomain = "fabrikam"
strUser = "bob"

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set objQuota = objWMIService.Get _
    ("Win32_DiskQuota.QuotaVolume='Win32_LogicalDisk.DeviceID=""" " & _

Enable Disk Quotas


Enables disk quotas for drive C on a computer.

For Each objDisk in colDisks
    objDisk.State = ENFORCE_QUOTAS
    objDisk.Put_
Next

Enable Disk Quotas on the Local Computer


Enables disk quotas for drive C on the local computer. To enable disk quotas for a different drive, change C:\ in line two to the appropriate drive letter (for example, D:\). To disable disk quotas, set the value of the constant ENABLE_QUOTAS to 0. To enable, but not enforce, disk quotas, set this value to 1. This script must be run on the local computer. 
Const ENABLE_QUOTAS = 2

Set colDiskQuotas = CreateObject("Microsoft.DiskQuota.1")
colDiskQuotas.Initialize "C:\", True
colDiskQuotas.QuotaState = ENABLE_QUOTAS
