Question

I’ve written this code to start a process:

var proc = new Process();
proc.StartInfo.Arguments = string.Format("{0} {1}", inputFilePath, outputFilePath);
proc.StartInfo.FileName = @Settings.GetImageMagickConvertPath();
proc.StartInfo.CreateNoWindow = false;
proc.StartInfo.UseShellExecute = false;
proc.Start();

This works perfectly locally. But when I put this code on a remote machine, this code no longer works (Error is “Access is denied” when trying to start the proc). So, I’ve added the credentials I use to connect using RDC (user/pass) in order to start the process:

proc.StartInfo.UserName = "user";

System.Security.SecureString secret = new System.Security.SecureString();

foreach (char c in "pass")
    secret.AppendChar(c);

proc.StartInfo.Password = secret;

but I still receive the same error…

Do you guys see anything which can be fixed for this issue?

Answer 1

Ok, it’s solved now.

Basically I had two issues:

1. The path to the process to start was incorrect (instead of folder/program.exe I put by mistake folder/ and I received “Access is denied” which made my life a nightmare (started to look for rights, account etc). Would have been nice if Microsoft have been improved this error like “The path to the process is wrong”).

2. I had to run it as a Local Service (app pool) instead of App Pool Identity. (and no need for Start Info credentials)
