Mapping DOS to a 2003 server

I have a machine that is DOS only we are moving to AD. THis DOS machine currently attaches to Novell via a mapping statement in the autoexec.bat. We are ditching novell and going AD any ideas on how to get this DOS machine to map to the 2003 server and see a folder? Any help is most welcomed

Updating the DOS box is not an option at this time

I don't know much about networking in DOS but it is totally possible to authenticate off AD and map/connect to a network share. I use Bart's Network Boot Disk to image up my computers at work. There is tons of info at: www.nu2.nu/bootdisk/network/ . Hope that helps...
