mountinf windows file system in dual boot

[Dave Martini 1]

I have a dual boot single disk system. RHEL 4 and Windows XP.
How do I mount my windows partition when I'm booted into the linux os.

When I do fdisk it shows

/dev/hda1   HPFS/NTFS
/dev/hda2   W95 Ext'd (LBA)

But when I try to mount it

# mount -t HPFS/NTFS /dev/hda1 /mnt/windows
mount: fs type HPFS/NTFS not supported by kernel.

Is it possible to mount an NTFS file system on Redhat?

Thank You.
