    hi,

    please see the code below

    DirectoryEntryAD = new DirectoryEntry("WINNT//:chd12323,computer");

    DirectoryEntry grp;

    grp = AD.Children.Find("Guests", "group");

     if (grp != null)

     try passing the directory object a user name and password with the appropriate permissions, as in...

    using (objAD = new DirectoryEntry())
    {
        objAD.Path = "WinNT://" + Environment.MachineName + ",Computer";
        objAD.Username = "yourWindowsUser";
        objAD.Password = "yourPassword";
        ....
    }
    
    p.s. - wrapping in a "using" will ensure the object is cleaned up properly - otherwise call dispose or close on the object when you are done.

    i found the error..

    we cannot use both LDAP and WinNT providers for a common operation.

    i replaced LDAP with WinNT and binded the object with WinNT now and its working..
