Calling CreateProcessWi thLogonW from asp.net

[Arne]

Hi,
I'm working on an asp.net application that reads a users username and
password, and starts a process with the username read.

The problem is that the program returns value 2(ERROR_FILE_NO T_FOUND).

Here's my code:

public class Class1
{
[DllImport("adva pi32.dll", CharSet=CharSet .Auto, SetLastError=tr ue)]
internal static extern bool CreateProcessWi thLogonW(String lpszUsername,
String lpszDomain, String lpszPassword, int dwLogonFlags, string
applicationName , string commandLine, int creationFlags, IntPtr environment,
string currentDirector y, ref STARTUPINFO sui, out PROCESS_INFORMA TION
processInfo);

[StructLayout(La youtKind.Sequen tial)]
internal struct STARTUPINFO
{
internal int cb;
[MarshalAs(Unman agedType.LPTStr )]
internal string lpReserved;
[MarshalAs(Unman agedType.LPTStr )]
internal string lpDesktop;
[MarshalAs(Unman agedType.LPTStr )]
internal string lpTitle;
internal int dwX;
internal int dwY;
internal int dwXSize;
internal int dwYSize;
internal int dwXCountChars;
internal int dwYCountChars;
internal int dwFillAttribute ;
internal int dwFlags;
internal short wShowWindow;
internal short cbReserved2;
internal IntPtr lpReserved2;
internal IntPtr hStdInput;
internal IntPtr hStdOutput;
internal IntPtr hStdError;
}

[StructLayout(La youtKind.Sequen tial)]
internal struct PROCESS_INFORMA TION
{
internal IntPtr hProcess;
internal IntPtr hThread;
internal int dwProcessId;
internal int dwThreadId;
}

const int LOGON_NETCREDEN TIALS_ONLY = 2;
const int CREATE_UNICODE_ ENVIRONMENT = 0x00000400;
const int NORMAL_PRIORITY _CLASS = 0x00000020;
const int STARTF_USECOUNT CHARS = 0x00000008;
private void Page_Load(objec t sender, System.EventArg s e)
{

//Method where i keep the html code that all pages use
Webmethods met = new Webmethods();

met.startPage() ;

string file = Page.Request.Pa rams.Get("filen ame");
string user = Page.Request.Pa rams.Get("usern ame");
string pw = Page.Request.Pa rams.Get("passw ord");
string domain = Page.Request.Pa rams.Get("domai n");
string cmdln = file +" param1 param2"; //file is c:\test.exe

PROCESS_INFORMA TION processInfo;

STARTUPINFO startInfo = new STARTUPINFO();

startInfo.cb = Marshal.SizeOf( startInfo);
startInfo.lpTit le = "Command console";
startInfo.dwFla gs = STARTF_USECOUNT CHARS;
startInfo.dwYCo untChars = 50;

bool ret = CreateProcessWi thLogonW(logonN ame, domain, password,
LOGON_NETCREDEN TIALS_ONLY, null, cmdln, NORMAL_PRIORITY _CLASS |
CREATE_UNICODE_ ENVIRONMENT, IntPtr.Zero, "C:\\", ref startInfo, out
processInfo);

if ( !ret )
{
Page.Response.W rite("<h3><tr>< td>Error:&nbsp" + Marshal.GetLast Win32Error()
+"</td></tr></h3>");
Page.Response.W rite("<h3><tr>< td>ErrorHR:&nbs p"+
Marshal.GetHRFo rLastWin32Error ()+"</td></tr></h3>");
}
else
Page.Response.W rite("<h3><tr>< td>ProcessID: {0}&nbsp" +
processInfo.dwP rocessId+"</td></tr></h3>");
met.endPage();
}
}

This is what my page prints:

Error: 2
ErrorHR: -2147024894

Any help would be appreciated

Sorry, little mistake:

in original code, the CreateProcessWi thLogonW method is called with
logonName = user and password = pw.
