iis 7 - Shared folder access with login & password impersonation - W2K8 IIS7 -

hope here.

i'm using impersonation login shared folder , works locally (win8). doens't work on win2k8 iis7 server.

following code used impersonation:

public sealed class wrappedimpersonation {     public enum logontype : int     {         interactive = 2,         network = 3,         batch = 4,         service = 5,         unlock = 7,         networkcleartext = 8,         newcredentials = 9     }      public enum logonprovider : int     {         default = 0,  // logon32_provider_default         winnt35 = 1,         winnt40 = 2,  // use ntlm logon provider.         winnt50 = 3   // use negotiate logon provider.     }      public enum impersonationlevel     {         securityanonymous = 0,         securityidentification = 1,         securityimpersonation = 2,         securitydelegation = 3     }      [dllimport("advapi32.dll", entrypoint = "logonuserw", setlasterror = true, charset = charset.unicode)]     public static extern bool logonuser(string lpszusername, string lpszdomain,         string lpszpassword, logontype dwlogontype, logonprovider dwlogonprovider, ref intptr phtoken);      [dllimport("kernel32.dll")]     public extern static bool closehandle(intptr handle);      [dllimport("advapi32.dll", charset = charset.auto, setlasterror = true)]     public static extern int duplicatetoken(intptr htoken, int impersonationlevel, ref intptr hnewtoken);      [dllimport("advapi32.dll", charset = charset.auto, setlasterror = true)]     public static extern bool reverttoself();      private string _domain, _password, _username;     private intptr _token;     private windowsimpersonationcontext _context;     private intptr _duplicatetoken;      private bool isincontext     {         { return _context != null; }     }      public wrappedimpersonation(string domain, string username, string password)     {         _domain = string.isnullorempty(domain) ? "." : domain;         _username = username;         _password = password;         _token = intptr.zero;     }      // changes windows identity of thread. make sure call leave() @ end.     [permissionset(securityaction.demand, name = "fulltrust")]     public void enter()     {         if (isincontext)             return;          _token = intptr.zero;         bool logonsuccessfull = logonuser(_username, _domain, _password, logontype.newcredentials, logonprovider.winnt50, ref _token);         if (!logonsuccessfull)         {             throw new win32exception(marshal.getlastwin32error());         }          duplicatetoken(_token, (int)impersonationlevel.securityimpersonation, ref _duplicatetoken);          windowsidentity identity = new windowsidentity(_duplicatetoken);         _context = identity.impersonate();          debug.writeline(windowsidentity.getcurrent().name);     }      [permissionsetattribute(securityaction.demand, name = "fulltrust")]     public void leave()     {         if (!isincontext)             return;          _context.undo();          if (_token != intptr.zero)         {             closehandle(_token);         }         _context = null;     } 

usage:

            var impersonationcontext = new wrappedimpersonation(_url, _login, _password);         impersonationcontext.enter();          list<string> files = directory.getfiles(_dataset.transfermethod.url).tolist();   impersonationcontext.leave(); 

server settings: local security policy -> local policies -> user rights assignments -> impersonate client after authentication : apppool identity need added here?

secondary logon service started.

error code on server: system.unauthorizedaccessexception: access path '\myserver\mysharedfolder' denied.

i've tried wnetaddconnection2 methods, these not sufficient if want switch between shares because blocks after while.

application: mvc.net .net version: 4.5

did got work on win2k8 iis7 machine?
