SecurityExcepti o nduring start of a new Process form Application under Windows Server 2003

[SMichal]

Hi, I've got a simple problem when I try to start a new process from my
application.
I'm starting a new process like this:

Process proc = new Process();
proc.StartInfo. Arguments = "";
proc.StartInfo. FileName = @"C:\Submit.bat ";
proc.StartInfo. CreateNoWindow = false;
proc.Start();
proc.WaitForExi t();

label1.Text = "ExitCode = " + proc.ExitCode.T oString();

....everything works fine, but only under Windows XP....when I start the same
application under Windows Server 2003, I'm getting this exception:

System.Security .SecurityExcept ion: Request failed.

....how can I set the Security for starting of a new process ?
