Question

I need execute a program in the remote computer, so I created a service in order to call psexec (it’s crucial using the service). However, this service cannot call psexec.

Following the code:

            String cmd = "", arguments = "";
            cmd = @"C:\PsTools\psexec.exe";

            arguments = @"\\remoteComputer -u "user" -p "password" "C:\program.exe"";

            Process process = new Process();
            process.StartInfo.FileName = cmd;
            process.StartInfo.Arguments = arguments;

            process.StartInfo.UseShellExecute = false;
            process.StartInfo.RedirectStandardOutput = true;
            process.StartInfo.RedirectStandardError = true;
            process.StartInfo.CreateNoWindow = true;
            process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

            process.Start();
            result = process.StandardOutput.ReadToEnd();
            sError = process.StandardError.ReadToEnd();

            result += "Program has finished its execution";

Do anyone know why the service cannot call the psexec?

I had issues with psexec hanging too when running a batch file remotely. How about WMI? This worked for me when running something on a remote computer; it works for *.bat and *.exe too. You might need to click Project>Add Reference and choose “System.Management” on the .NET tab–the reference wasn’t there in VS 2010 until I manually added it.

        System.Management.ConnectionOptions connOptions =
            new System.Management.ConnectionOptions();

        connOptions.Impersonation = System.Management.ImpersonationLevel.Impersonate;
        connOptions.EnablePrivileges = true;

        string compName = "RemoteComputerName";
        System.Management.ManagementScope manScope =
            new System.Management.ManagementScope(
                String.Format(@"\\{0}\ROOT\CIMV2", compName), connOptions);
        manScope.Connect();

        System.Management.ObjectGetOptions objectGetOptions =
            new System.Management.ObjectGetOptions();

        System.Management.ManagementPath managementPath =
            new System.Management.ManagementPath("Win32_Process");

        System.Management.ManagementClass processClass =
            new System.Management.ManagementClass(manScope, managementPath, objectGetOptions);

        System.Management.ManagementBaseObject inParams =
            processClass.GetMethodParameters("Create");

        inParams["CommandLine"] = @"c:\MyBatchFile.bat";

        System.Management.ManagementBaseObject outParams =
            processClass.InvokeMethod("Create", inParams, null);
