I just had the very same issue not related to NBU AFAIK.  Client OS W2K8.

Instead of rescanning from disk mgmt and seeing the extra space there, 
then launching diskpart to extend like I normally do, I ran rescan 
command inside diskpart and did extend. Volume shows as taking up all 
the space in diskmgmt, but my computer didn't show the space. In the end 
I added an extra GB disk space and did what I normally do and the volume 
showed the expected size in my computer afterwards. Wierd. Not sure what 
happened. It was a test VM system so I didn't worry too much about t.
