The personification mode of the external program mode

We have an outdated CRM system (Server) that uses a mapped network drive. The problem is that the disk is fully open for modification by all users.

I am trying to use user impersonation in a C # .net console application (client A).

  • Client A runs the .exe program (console application), which does the impersonation (domain, other user, password).

  • Then the console application displays the network folder on the disk:

    
    NETRESOURCE nr = new NETRESOURCE();
    nr.dwType = ResourceType.RESOURCETYPE_DISK;
    nr.lpLocalName = "X:";
    nr.lpRemoteName = @"\\x.x.x.x\folderx";
    nr.lpProvider = null;

    int result = WNetAddConnection2(nr, null, null, 0);
  1. Then the console application will try to open the .exe program located in the mapped network drive.
    
    Process ExternalProcess = new Process();
    ExternalProcess.StartInfo.FileName = @"X:\subfolder\APP\app.exe"; // Window application
    ExternalProcess.StartInfo.WindowStyle = ProcessWindowStyle.Maximized;
    ExternalProcess.Start();
    ExternalProcess.WaitForExit();

But I get a Win32Exception:

    

    Unknown error (0xfffffffe)

Folder sharing properties use a user personifying himself as the only user who can read and write.
