that sucks, doesn't it? well, if you have smbfs compiled into your kernel, try mounting the share with smbmount, or, depending on your partitioning scheme tar your individual filesystems one at a time and bounce the tarballs around, or use
Ghost4Unix to create an image and send it to an FTP server....sorry, but it's easier to find a free/inexpensive ftp server for windows than it is to find a free/inexpensive NFS server for windows.
