The easiest way is probably an ftp installation.
Set up an ftp server (like Filezilla Server [http://prdownloads.sourceforge.net/f...5.exe?download
on your Windows PC and have it use the DVD as its root.
Get the network floppy images from the install\images directory of the DVD and use rawwrite from the dosutils dir
to put them on floppies.
Boot your other PC with the floppies and select FTP install. Enter the ip of your Windows PC and select "/" as Mandrake dir.
