Hi All

I have been writing an application to get the details of remote machine like OS Name, Logon User Name etc using WMI Classes.

In our network we have machines with Windows XP, Windows Vista Windows 7.

I am able to get the informations for all windows 7 and windows vista machines.

But the problem here is i am not able to get the informations for windows XP machines.
Every time i am getting the following exception
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

I have gone through the net but no help. I have done all the steps mentioned in the following link
But no luck still i am not able to solve the problem.
I have domain username with administrator privilages.
Below is the code that i have used. (C#)
private void GetRemoteComputerInfo(string compName)
            ObjectGetOptions oc = new ObjectGetOptions();
            try {
                ConnectionOptions connOptions = new ConnectionOptions();
                connOptions.Username = "domain\\domainUserName";
                connOptions.Password = "domainUserPass";
                connOptions.Authority = "kerberos:domain\\" + compName;
                connOptions.Impersonation = ImpersonationLevel.Impersonate;
                connOptions.EnablePrivileges = true;
                ManagementScope msc;
                if (compName == Environment.MachineName)
                    msc = new ManagementScope("\\\\" + compName + "\\root\\cimv2");
                    msc = new ManagementScope("\\\\" + compName + "\\root\\cimv2", connOptions);
                ManagementClass mc = new ManagementClass("Win32_ComputerSystem");
                mc.Scope = msc;
                //collection to store all management objects
                ManagementObjectCollection moc = mc.GetInstances();
                if (moc.Count != 0) {
                    foreach (ManagementObject mo in mc.GetInstances()) {
                        Console.WriteLine(string.Format("\nMachine Make: {0}\nMachine Model: {1}  System Type: {2}  Host Name: {3}  Logon User Name: {4}{5}",
            catch (Exception e) {
                Console.WriteLine("{0}: {1}", e.GetType().Name, e.Message);
