Question

We have a .exe which we need to execute at the time an order is placed on a website. When
we test this locally it works fine using IIS Express. When we move it to IIS, it fails. We assume this is a permissions error as if we set the App Pool to run as the administrator then the script works again. The question we have is how do we execute the .exe as the administrator whilst the App Pool is ApplicationIdentity? We are using the following code:

var process = new Process
                          {
                              StartInfo = new ProcessStartInfo
                                              {
                                                  FileName = executablePath,
                                                  Arguments = argumentList,
                                                  Domain = domain,
                                                  UserName = userName,
                                                  Password = securePassword,
                                                  UseShellExecute = false,
                                                  LoadUserProfile = true
                                              }
                          };

        process.Start();
        process.WaitForExit();
        process.Close();

The .exe is trying to write to the Users AppData folder which is why it fails. It is a 3rd party app so we cannot change the source code.

EDIT: Just to clarify also, when we specify the username and password in procmon it still appears to run from ISUR.

Answer 1

We fixed this by enabling User profile on IIS AppPool and setting permission for the IIS user on the folder it was trying to write to.

We sue ProcMon to find where the program was failing and the folder it was trying towrite to was C:\Windows\System32\config\systemprofile
