Hi,

I was using below code to change password for windows account. This code is working in localhost and not in IIS.
I noticed in IIS, when i changed the DefaultAppPool identity to LocalSystem it is working. But, My app pool identity is ApplicationPoolIdentity. it is not working

Process QProc = new Process();
                // Do Something To hide Command(cmd) Window
                QProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
                QProc.StartInfo.CreateNoWindow = true;

                // Call Net.exe
                QProc.StartInfo.WorkingDirectory = "C:\\windows\\SYSTEM32";
                //QProc.StartInfo.WorkingDirectory = filePath;
                QProc.StartInfo.FileName = "net.exe";
                QProc.StartInfo.UseShellExecute = false;
                QProc.StartInfo.RedirectStandardError = true;
                QProc.StartInfo.RedirectStandardInput = true;
                QProc.StartInfo.RedirectStandardOutput = true;

                // Prepare Command for Exec
                QProc.StartInfo.Arguments = @" user " + txtUserName.Text + "  " + txtPassword.Text;
                QProc.Start();

Hi,

More likely a permission issue. You don't have an exception or error message to confirm that ?

If this is to change the user password I would rather use https://docs.microsoft.com/en-us/dotnet/api/system.directoryservices.accountmanagement.authenticableprincipal.setpassword?redirectedfrom=MSDN&view=netframework-4.7.2#System_DirectoryServices_AccountManagement_AuthenticablePrincipal_SetPassword_System_String_

You can also connect to AD using a dedicated account so that your app doesn't generally have this permission.
