Hi Everybody,

I have a project that copies files from a computer to another .I am using Impersonator for this. But it works only in same domain. İ want to copy file to another domain.
Here is my codes

public Impersonator(
          string userName,
          string domainName,
          string password)
      {
          ImpersonateValidUser(userName, domainName, password);
      }

      public void Dispose()
      {
          UndoImpersonation();
      }
