Invoking process under different user from ASP.NET web service RRS feed

  • Question

  • Is there a way to run process as different user from ASP.NET rest API web application which runs as service.

    If impersonation used before calling System.Diagnostic.Proccess.Start() it does not execute it under impersonated user.

    However, if explicitly set username, password into ProcessInfo property that still does not execute – Access Denied:

    if (!string.IsNullOrEmpty(userName))


                        process.StartInfo.UserName = userName;


                        if (!string.IsNullOrEmpty(domain))


                            process.StartInfo.Domain = domain;




                    if (!string.IsNullOrEmpty(password))


                        process.StartInfo.PasswordInClearText = password;


                    process.StartInfo.LoadUserProfile = false;

                    process.StartInfo.WorkingDirectory = @"C:\working";

                    process.StartInfo.CreateNoWindow = true;

                    process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

                    process.StartInfo.UseShellExecute = false;

                    process.StartInfo.RedirectStandardError = true;

                    process.StartInfo.RedirectStandardOutput = true;

                    process.StartInfo.LoadUserProfile = false;

                    var stdOutput = new StringBuilder();

                    process.OutputDataReceived += (sender, args) => stdOutput.Append(args.Data);

                    string stdError = null;



                        cmdExecmodle.OutputResult = " " + RuntimeInformation.OSDescription + "\r\n";

                        cmdExecmodle.OutputResult += " " + RuntimeInformation.ProcessArchitecture.ToString() + "\r\n";

                        cmdExecmodle.OutputResult += " " + WindowsIdentity.GetCurrent().Name + "\r\n";




                        if (waitForExit)









                    catch (Exception e)


                        throw new Exception("OS error while executing " + Format(filename, arguments) + ": " + e.Message, e);


    If this is run from debug and/or IISExpress it works properly.

    I've tried running service both under Local System and Administrator too. Also, I've been giving additional permissions to Administrator like:

    • Log on as a service Act as part of the operating system Adjust memory quotas for a process Replace a process level token

    which did not helped.

    Any ideas?

  • Hi ljubop,

    Since this thread is related to ASP.NET, so I suggest that you can ask this question in the ASP.NET forum for better support.

    The Visual C# forum discusses and asks questions about the C# programming language, IDE, libraries, samples, and tools.
