RHEL does not support the NTFS filesystem out of the box so visit;
http://www.linux-ntfs.org/
If you want read/write access then you need to install a new custom kernel (from kernel.org the 2.6.19.2 source) and configure support for FUSE in the kernel and use the fuse and ntfs-3g source rpm packages.
Or create a FAT32 partition to share data.
Sample /etc/fstab entry for read only ntfs access;
Code:
/dev/hda1 /mnt/WindowsXP ntfs noauto,umask=0,users,ro 0 0
For the details see; man fstab (and) man mount
