C# System.Diagnostics.Process launches on my local IIS, but doesn't launch on the server -

i'm trying make program run bat file, launches exe file. works fine on local computer, doesn't work on server iis. doesn't work regardless of whether specify username , password in processstartinfo or not. i've searched forums , applied different stuff, none of them help.

in windows event viewer doesn't give me errors process output. if change directory , can't find bat file, output gives me error, when finds file, doesn't return , doesn't launch program.

now, if provide credentials process, specifying psi.domain, psi.username , psi. password, standartoutput doesn't return error, windows events gives me 2 following errors:

application popup: cmd.exe - application error : application unable start correctly (0xc0000142). click ok close application.

and

application popup: conhost.exe - application error : application unable start correctly (0xc0000142). click ok close application.

here's code:

    system.diagnostics.processstartinfo psi = new system.diagnostics.processstartinfo(@"c:\inetpub\copytoad\pspasswd\passchange.bat");                                 psi.redirectstandardoutput = true;                 psi.redirectstandardinput = true;                 psi.redirectstandarderror = true;                 psi.createnowindow = true;                                 psi.windowstyle = system.diagnostics.processwindowstyle.hidden;                 psi.useshellexecute = false;                 system.diagnostics.process listfiles;                 listfiles = new system.diagnostics.process();                 listfiles.enableraisingevents = false;                 listfiles.startinfo = psi;                  listfiles.start();                  system.io.streamreader myoutput = listfiles.standardoutput;                 listfiles.waitforexit(2000);                 myoutput.readtoend();                 string output = myoutput.readtoend();                 viewbag.view6 += output + "***";                 if (listfiles.hasexited)                 {                     output = myoutput.readtoend();                     viewbag.view6 += output;                 }
