Run script (.bat) from ASP.Net with elevated privileges

I have a ASP.Net application from which I want to run several (BAT) scripts that require elevated privileges, because it must start and stop services, copy files, etc ...

I've tried to apply different approaches, but I can't find one that works.

This is the code from ASP.Net c#:

var securePass= new SecureString();
string password = "AdminPassword";
for (int x = 0; x < password.Length; x++)
{
  pass.AppendChar(password[x]);
}

Process p = new Process();
p.StartInfo.FileName = Path.Combine(appPath, "Scripts", "ServiceTest.bat");
p.StartInfo.Arguments = "";
p.StartInfo.UseShellExecute = false;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UserName = adminUserName;
p.StartInfo.Domain = adminDomain;
p.StartInfo.Password = securePass;
p.StartInfo.Verb = "runas";
p.Start();
p.WaitForExit();

This is the ServiceTest.bat:

NET START MSSQL$SQLEXPRESS

It not works: If I remove "p.StartInfo.CreateNoWindow" and "p.StartInfo.RedirectStandardOutput" lines, the console window shows "Access denied" error executing "NET START MSSQL$SQLEXPRESS".

I tried with Filename "cmd.exe", and "/c "+Path.Combine(appPath, "Scripts", "ServiceTest.bat") as arguments, and several ways but it not work.

Any suggestion?

Thanks for your time!

You have to use different credentials. For that use RunAs or PSExec

E.g.
PsExec64.exe \\<local machine Name> -u Domain\Administrator -p <Password> "<Script Name>"
