It's generally recommended to use Windows tools to do NTFS re-sizing.
I tend to disagree with that advice... I would recommend http://gparted.org/livecd.php over the microsoft-supplied tools, in a heartbeat.
Boot off that Live image on a CD or thumbdrive (or use the version of GPartEd included with the System Rescue Live CD from http://www.sysresccd.org/ ), select the correct disk from the drop down menu in the upper-right, set the borders of the partitions where you want them with the GUI, then tell it to Apply the pending actions.
If I recall correctly, the disk management tool in the windows MMC won't resize the partition it's running from, by the way.
