finally figured this out code is as follows for anyone interested... DiskQuotaControl dqcc = new DiskQuotaControl(); dqcc.Initialize(@e:\  true); foreach(DIDiskQuotaUser x in dqcc) { Console.WriteLine(Account Container Name {0} x.AccountContainerName); Console.WriteLine(Account Status {0} x.AccountStatus); Console.WriteLine(Display Name {0} x.DisplayName); Console.WriteLine(ID {0} x.ID); Console.WriteLine(Logon Name {0} x.LogonName); Console.WriteLine(Quota Limit {0} x.QuotaLimit); Console.WriteLine(Quota Limit Text {0} x.QuotaLimitText); Console.WriteLine(Quota Threshold {0} x.QuotaThreshold); Console.WriteLine(Quota Threshold Text {0} x.QuotaThresholdText); Console.WriteLine(Quota Used {0} x.QuotaUsed); Console.WriteLine(Quota Used Text {0} x.QuotaUsedText); Console.WriteLine(); } this just iterates through all quotad users and prints the results to the console. Hope this help someone!

Hi zespri The code works but throws up a unhandled win32 exception... The quota is implemented when you look... code is as follows: string userName = Test User2; string password = abcdefg; string quotaDriveLetter = @C:\; long quotaLimit = 52428800; //50MB long quotaWarning = 47185920; //45MB DiskQuotaControlClass dqcc = new DiskQuotaControlClass(); dqcc.Initialize(quotaDriveLetter  true); DIDiskQuotaUser dqnew = dqcc.AddUser(userName); dqnew.QuotaLimit = quotaLimit; dqnew.QuotaThreshold = quotaWarning; any ideas ? The host machine is XP Pro...

Try the following run tlbimp c:\windows\system32\dskquota.dll /out:c:\DskQuotaTypeLib.dll (change the path to *your* system32 directory) In Visual Studio project add c:\DskQuotaTypeLib.dll as areference Write a code similar to the following: using System; using DskQuotaTypeLib; namespace QuotaTest { class Class1 { [STAThread] static void Main(string[] args) { DIDiskQuotaControl quota = new DiskQuotaControlClass(); quota.Initialize(@C:	rue); DIDiskQuotaUser user = quota.AddUser(Administrator); user.QuotaLimit = 1024*1024*5; user.QuotaThreshold = -1; } } }
