Application not running from production web server

I have to run a tool from our internal website. There are few inputs that user will provide from UI and then I want to run the tool with user credential. My code works fine when I run it from my local machine, but when I deploy it to production server and try to execute it from there it does not start anything.

Here is my code, any advice will be greatly appreciated.

            System.Diagnostics.ProcessStartInfo PSI = new Syste开发者_运维知识库m.Diagnostics.ProcessStartInfo(@"D:\run.bat");             
            PSI.UserName = "username";
            PSI.Domain = "domain";
            System.Security.SecureString securePwd = new System.Security.SecureString();
            string password = "password";
            foreach (char c in password)
            {
                // Append the character to the password.
                securePwd.AppendChar(c);
            }
            PSI.Password = securePwd;
            PSI.UseShellExecute = false;
            process.StartInfo = PSI;
            PSI.Arguments = SiteId.Text + " " + WebServiceUrl.Text + " " +LogFile.Text;
            process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
            process.Start();

First:

• Check the identity of your application pool (advanced settings).
• Switch the identity to "system" and see if the batch file runs from the web app.

If it does:

• Change the identity back to network service,
• Make sure your batch file has execute permissions applied for user Network Service (or whichever identity you chose)

If it doesn't:

• Try opening the file with your code and appending some harmless text to the end.
• If that works, you can at least rule out permissions and web-app view-ability concerns.

I want to close this thread as my problem of running an application from production server solved. But I'm facing issue to run that application using specific user name & password. It always run with whatever identity is set in apppool. So for now if I only use this line it works on app pool default identity

Process.Start("notepad");

But if I use this line of code it don't even start a notepad in that server

            string password = "XXXXX";
            System.Security.SecureString securePwd = new System.Security.SecureString();
            foreach (char c in password)
            {
                // Append the character to the password.
                securePwd.AppendChar(c);
            }
            Process.Start("notepad", "username", securePwd, "domain");

I'm going to ask a separate question on this. Thanks for all who replied.
