Batch FTP to Win2000 server using active directories

I am trying to use a batch FTP from the AS400 to a Win2000 FTP server that is 
using active directories.  The PF I am using for my input looks like this:

DOMAIN\USER PASSWORD
ASCII
PUT as400lib/file  /dir/file.txt

When I use this same format to a different server, without the DOMAIN it works 
fine.  The problem is that the new FTP server requires the DOMAIN and when I 
pass it along with the user, the FTP server never receives the password and it 
errors, like below.

Output redirected to a file.
Input read from specified override file.
Connecting to host Servername.Domain.com at address xxx.xxx.xxx.xxx using port 
xx.
220 Servername Microsoft FTP Service (Version 5.0).
Enter login ID (default):
331 Password required for DOMAIN\USER.
530 User DOMAIN\USER cannot log in.
Enter an FTP subcommand.
> ASCII
530 Please login with USER and PASS.
Enter an FTP subcommand.
> PUT AS400lib/file  /dir/file.txt
You must first issue the USER subcommand.
Enter an FTP subcommand.
„«       QUIT

When I log in manually I have no problem using the domain\user format, it is 
only the batch FTP that is giving me the problem.  I have not found any 
documentation on how to handle this.  Has anyone else encountered and solved 
this problem?  If so could you share the solution, please?
